Perl::Critic::Policy::Variables::ProhibitAugmentedAssignmentInDeclaration(3)
NAME
Perl::Critic::Policy::Variables::ProhibitAugmentedAssignmentInDeclaration
- Do not write " my $foo .= 'bar'; ".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Variable declarations that also do initialization with '=' are common.
Perl also allows you to use operators like '.=', '+=', etc., but it it
is more clear to not do so.
my $foo .= 'bar'; # same as my $foo = 'bar';
our $foo *= 2; # same as our $foo = 0;
my ( $foo, $bar ) += ( 1, 2 ); # same as my ( $foo, $bar ) = ( undef, 2 );
local $Carp::CarpLevel += 1; # same as local $Carp::CarpLevel = 1;
state $foo += 2; # adds 2 every time it's encountered
Such constructs are usually the result of botched cut-and-paste, and
often are bugs. Some produce warnings.
CONFIGURATION
This Policy is not configurable except for the standard options.
