NAME
       Perl::Critic::Policy::Freenode::ConditionalImplicitReturn - Don't end a subroutine with a conditional
       block


DESCRIPTION
       If the last statement in a subroutine is a conditional block such as "if ($foo) { ... }", and the "else"
       condition is not handled, the subroutine will return an unexpected value when the condition fails, and it
       is most likely a logic error. Specify a return value after the conditional, or handle the "else"
       condition.

         sub { ... if ($foo) { return 1 } }                   # not ok
         sub { ... if ($foo) { return 1 } return 0 }          # ok
         sub { ... if ($foo) { return 1 } else { return 0 } } # ok

       This policy only applies if the subroutine contains a return statement with an explicit return value,
       indicating it is not intended to be used in void context.


CAVEATS
       This policy currently only checks for implicitly returned conditionals in named subroutines, anonymous
       subroutines are not checked. Also, return statements within blocks, other than compound statements like
       "if" and "foreach", are not considered when determining if a function is intended to be used in void
       context.


AFFILIATION
       This policy is part of Perl::Critic::Freenode.


CONFIGURATION
       This policy is not configurable except for the standard options.
