Perl::Critic::Policy::Tics::ProhibitUseBase

NAME

Perl::Critic::Policy::Tics::ProhibitUseBase - do not use base.pm

VERSION

version 0.010

DESCRIPTION

use base qw(Baseclass);

You’ve seen that a hundred times, right? That doesn’t mean that it’s a good idea. It screws with $VERSION, it alters (for the worse) the exceptions reported by failure-to-require, it doesn’t let you call the base class’s "import" method, it pushes to @INC rather than replacing it, and it uses and documents interactions with fields, which can lead one to believe that fields are even remotely relevant to modern (or any!) development of Perl classes.

There are a lot of ways around using "base". Pick one.

PERL VERSION

This library should run on perls released even a long time ago. It should work on any version of perl released in the last five years.

Although it may work on older versions of perl, no guarantee is made that the minimum required version will not be increased. The version may be increased for any reason, and there is no promise that patches will be accepted to lower the minimum required perl.

WARNING

This policy caused a bit of controversy, largely in this form:

These behaviors are either correct or can be worked around, and using base.pm
protects you from the problem of remembering to load prereqs and from
setting @INC at runtime.

These are true statements. My chosen workaround for all these problems is to not use base.pm. That doesn’t mean it’s a good idea for you, or anyone else. Heck, it doesn’t mean it’s a good idea for me, either. It’s just my preference. As with all Perl::Critic policies, you should decide whether it’s right for you.
