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.

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitMixedBooleanOperators - Write " !$foo && $bar || $baz " instead of " not $foo && $bar
       or $baz".

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Conway advises against combining the low-precedence booleans ( "and or not" ) with the high-precedence boolean operators ( "&& || !" ) in
       the same expression.  Unless you fully understand the differences between the high and low-precedence operators, it is easy to misinterpret
       expressions that use both.  And even if you do understand them, it is not always clear if the author actually intended it.

	   next if not $foo || $bar;  #not ok
	   next if !$foo || $bar;     #ok
	   next if !( $foo || $bar ); #ok
