• use strict; use warnings;
• use warnings; use strict;

Please explain why below.

Update: Credits use strict; before/after use warnings; and Re^2: use strict; before/after use warnings;.

• use 5.18.3; use warnings;

How many know that 5.12.0 was the first release that implies strict with use version? (well, actually 5.11.0, but I hope nobody is using 5.11.x in production code)

(I don't care what version notation is used)

As mentioned here, there might be some other options including -w and -W for warnings, and the implicit strict with use VERSION, but that would make a lot of possible answers if you were to enumerate all possible combinations...

And to answer the question, I put the more significant first, so version first (optional), because it is actually strict + features + minimal version, then strict (even after a version) because it is more restrictive (but less rewarningsive) than warnings, and at last warnings.

Edit: Oh, and if there's a package name, I always waste a few minutes deciding where I should put it, and then always add it after strict and warnings.

PS: at least that's what I keep telling my colleagues ;-)

Although it could be argued that

use strict;
use warnings;
[download]

is actually an attempt to

use less brain;
[download]

as it's a call for perl to do some of the thinking for you :)

Some people try to keep their use ...; declarations alphabetically sorted, saying that might help merges when multiple people add different uses... If one was to follow that route, use strict; would come before use warnings;.

I quite often sort them on length. Just a silly example:

use 5.18.2;
use warnings;

use Carp;
use DB_File;
use DateTime;
use Data::Peek;
use File::Glob;
use XML::Simple;
use Time::HiRes;
use Text::CSV_XS;
use Sys::Hostname;
use Tie::Hash::DBD;
use File::Basename;
use Module::Refresh;
use Module::CoreList;
use HTML::TreeBuilder;
use DateTime::TimeZone;
use Proc::ProcessTable;
use Encode qw(encode decode);

Ah yes, having so many use statements in a single file that you have to sort them to make them manageable, that happens all the time :'(. And having to add a bunch of modules in one go is common enough that two people do it in parallel on a daily basis. So annoying :/

In the starting year I'll want to learn:

• perl
• doing perl modules
• threading with or without MCE
• PDL
• how to hack WebPerl
• mastering regexes
• wiring Raspberry Pi
• arduino
• git to contribute to perl projects
• javascript (uh! ;)
• other (please specify)

I use postfix dereferencing

• Always
• Never
• Always on perls where it is no longer experimental
• Sometimes such as when I deem the syntax to be clearer with it than without
• Only if the existing codebase uses it or standards doc mandates it
• Arbitrarily/Randomly
• Never heard of it
• I'm still supporting 5.6.0, you insensitive clod!

• Only when replying to a dereference related question on PerlMonks or StackOverflow.
  map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

After Perl5, I'm mostly interested in:

• Assembly
• C
• Cobol
• C#
• C++
• D
• Dart
• Fortran
• Go
• Haskell
• Java
• JavaScript
• Kotlin
• Lisp
• Lua
• Matlab
• Nim
• Objective C
• Perl6
• PHP
• Python
• R
• Ruby
• Rust
• Scala
• Scheme
• Smalltalk
• Swift
• Unixish Shell Scripting languages
• Visual Basic
• Other (post in comments)

(To get the other side of What programming language do you hate the most?)

In 2019 the site I miss most is

• use.perl.org
• annocpan.org

When choosing a delimiter for Quote and Quote like Operators I:

• use a pair of delimiters {} () <> [] as often as possible
• use / when it's a regex
• just avoid # and it's fine
• choose whatever's not present in my string
• carefully select a delimiter that makes my OBFU even more confusing
• only use \ because I hate you
• delimit strings with my bare hands
• don't use quote-like operators
• follow several rules to increase clarity, consistency and maintanability and my pay-check
• start complaining; stop expecting me to make a decision and Do What I Mean already!

I use the ; in SQL statements, so I can easily copy-paste :)

my $sth = $dbh->prepare (qq;
    select foo, bar
    from   wobble
    where  barney = 42;
    );

"Hello world!" counts.

But please note: This question might be hard to bear because it looks like Go isn't a TMTOWTDI language.

Great. May i ask if you ever had an intern? Best regards, Karl

Why isn't there Inline::Go?
