Sommaire

NAME

Perl::Critic::Policy::ControlStructures::ProhibitCStyleForLoops - Write "for(0..20)" instead of "for($i=0; $i<=20; $i++)".

AFFILIATION

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

DESCRIPTION

The 3-part "for" loop that Perl inherits from C is butt-ugly, and only really necessary if you need irregular counting. The very Perlish ".." operator is much more elegant and readable. 
     for($i=0; $i<=$max; $i++){      #ick!
         do_something($i);
     }
 
     for(0..$max){                   #very nice
         do_something($_);
     }

CONFIGURATION

This Policy is not configurable except for the standard options.
