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.
