use parent qw( Tie::StdArray)

rlauer has asked for the wisdom of the Perl Monks concerning the following question:

Good day Monks! I seek some wisdom as I try to "do things the right way" perlcritic doesn't like when we use @ISA explicitly...but this dog don't hunt:

use Tie::Array;

use parent qw(Tie::StdArray);
[download]

I realize that Tie::StdArray is a module within Tie::StdArray so:

use parent qw(Tie::StdArray);
[download]

...doesn't hunt either... ...am I relegated to:

use vars qw(@ISA);
@ISA = qw (Tie::StdArray);  ## no critic (ProhibitExplicitISA)
[download]

???? - I know that perlcritic isn't always spot on, but before I ## no critic this chunk I will attempt to be enlightened. Thanks for shining some light on an otherwise dark room

I guess you're looking for the `-norequire` switch which allows to define a parent relationship without causing Perl to look for the wrong module: `package My::Array { use Tie::Array; use parent -norequire, qw(Tie::StdArray); }` [download]	[reply] [d/l]

dog don't hunt I assume you mean "it gave me an error that it couldn't locate Tie/StdArray.pm in @INC". Sharing error messages helps us to help you better than any variant of the phrase "it doesn't work". parent shows an example of how to have a parent of Tie::StdHash. Did you try to use that same pattern with Tie::StdArray? Because using `-norequire` option worked for me. `C:\usr\local\share > perl -MTie::Array -le "use parent qw(Tie::StdArray)" Can't locate Tie/StdArray.pm in @INC (you may need to install the Tie: +:StdArray module) (@INC contains: ...) BEGIN failed--compilation aborted at -e line 1. C:\usr\local\share > perl -MTie::Array -le "use parent -norequire => 'Tie::StdArray'"` [download]	[reply] [d/l] [select]

Thanks to the Monks for shedding light on this issue. I will study the docs on parent...thanks again.</P	[reply]
