NAME

       Perl::Critic::Policy::BuiltinFunctions::ProhibitComplexMappings - Map blocks should have a single statement.

AFFILIATION

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

DESCRIPTION

       The map function can be confusing to novices in the best of circumstances.  Mappings with multiple statements are even worse.  They're also
       a maintainer's nightmare because any added complexity decreases readability precipitously.  Why?  Because map is traditionally a one-liner
       converting one array to another.  Trying to cram lots of functionality into a one-liner is a bad idea in general.

       The best solutions to a complex mapping are: 1) write a subroutine that performs the manipulation and call that from map; 2) rewrite the
       map as a for loop.

CAVEATS

       This policy currently misses some compound statements inside of the map.  For example, the following code incorrectly does not trigger a
       violation:

	   map { do { foo(); bar() } } @list

CONFIGURATION

       By default this policy flags any mappings with more than one statement.	While we do not recommend it, you can increase this limit as
       follows in a .perlcriticrc file:

	   [BuiltinFunctions::ProhibitComplexMappings]
	   max_statements = 2
