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

CONFIGURATION

       This Policy is not configurable except for the standard options.

NAME

       Perl::Critic::Policy::ValuesAndExpressions::ProhibitVersionStrings - Don't use strings like "v1.4" or "1.4.5" when including other modules.

AFFILIATION

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

DESCRIPTION

       Whenever you "use" or "require" a module, you can specify a minimum version requirement.  To ensure compatibility with older Perls, this
       version number should be expressed as a floating-point number.  Do not use v-strings or three-part numbers.  The Perl convention for
       expressing version numbers as floats is: version + (patch level / 1000).

	   use Foo v1.2    qw(foo bar);  # not ok
	   use Foo 1.2.03  qw(foo bar);  # not ok
	   use Foo 1.00203 qw(foo bar);  # ok

CONFIGURATION

       This Policy is not configurable except for the standard options.
