NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitBooleanGrep - Use "List::MoreUtils::any" instead of "grep" in boolean context.

AFFILIATION

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

DESCRIPTION

       Using "grep" in boolean context is a common idiom for checking if any elements in a list match a condition.  This works because boolean
       context is a subset of scalar context, and grep returns the number of matches in scalar context.  A non-zero number of matches means a
       match.

       But consider the case of a long array where the first element is a match.  Boolean "grep" still checks all of the rest of the elements
       needlessly.  Instead, a better solution is to use the "any" function from List::MoreUtils, which short-circuits after the first successful
       match to save time.

CONFIGURATION

       This Policy is not configurable except for the standard options.

CAVEATS

       The algorithm for detecting boolean context takes a LOT of shortcuts.  There are lots of known false negatives.	But, I was conservative in
       writing this, so I hope there are no false positives.
