Perl::Critic::Policy::Variables::ProtectPrivateVars(3) User Contributed Perl Documentation Perl::Critic::Policy::Variables::ProtectPrivateVars(3)NAME
Perl::Critic::Policy::Variables::ProtectPrivateVars - Prevent access to private vars in other packages.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
By convention Perl authors (like authors in many other languages) indicate private methods and variables by inserting a leading underscore
before the identifier. This policy catches attempts to access private variables from outside the package itself.
CONFIGURATION
This Policy is not configurable except for the standard options.
HISTORY
This policy is inspired by a similar test in B::Lint

Perl::Critic::Policy::Variables::RequireNegativeIndices(User Contributed Perl DocumentPerl::Critic::Policy::Variables::RequireNegativeIndices(3pm)NAME
Perl::Critic::Policy::Variables::RequireNegativeIndices - Negative array index should be used.
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Conway points out that
$arr[$#arr];
$arr[$#arr-1];
$arr[@arr-1];
$arr[@arr-2];
are equivalent to
$arr[-1];
$arr[-2];
$arr[-1];
$arr[-2];
and the latter are more readable, performant and maintainable. The latter is because the programmer no longer needs to keep two variable
names matched.
This policy notices all of the simple forms of the above problem, but does not recognize any of these more complex examples:
$some->[$data_structure]->[$#{$some->[$data_structure]} -1];
my $ref = @arr;
$ref->[$#arr];
CONFIGURATION
This Policy is not configurable except for the standard options.

Trying to get a better handle on variables. ie how $1, $2, $3... are used. I have tried searching this site without much luck. When it would be used in how is $1 used in a program? I know you can asign variables x=4, just do not understand $1, $2.
