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.
