hello, again
I noticed $hash arg not passed to functions. You don't see outputs of print statement, do you? Would you try this?
#!/usr/bin/perl
use strict; use warnings;
use Benchmark qw(:all);
my %h;
@h{'A'..'Z','a'..'z'} = 1..52;
sub verbose {
#my $hash = shift;
foreach my $key (sort keys %h) {
print "$key: $h{$key}\n";
}
}
sub idiom {
#my $hash = shift;
print map "$_: $h{$_}\n", sort keys %h;
}
my %tests = (
'01_verbose' => \&verbose,
'02_idiom' => \&idiom,
);
cmpthese(
-10, #for 10 cpu secs
\%tests
);
__DATA__
Rate 02_idiom 01_verbose
02_idiom 5341/s -- -4%
01_verbose 5577/s 4% --
Personally, I like map.
regards.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
