NAME

Perl::Critic::Policy::Variables::NameReuse - Don't reuse names for different types of variables

SYNOPSIS

  perlcritic --single-policy=Variables::NameReuse script.pl
  perlcritic --single-policy=Variables::NameReuse lib/

  # .perlcriticrc
  severity = 1
  only = 1
  [Variables::NameReuse]

DESCRIPTION

This policy checks for the existence of multiple variables with the same name in a file. This can be confusing especially when accessing elements of variables or using list or key-value slices. For example, the code could access both $foo and $foo[0] but these actually refer to the unrelated variables $foo and @foo.

  my $foo = @foo;             # not ok
  my @bar = @bar{'a','b'};    # not ok
  my $count = @foo;           # ok
  my @values = @bar{'a','b'}; # ok

AFFILIATION

This policy has no affiliation.

CONFIGURATION

This policy is not configurable except for the standard options.
