NAME
Perl::Critic::Policy::ControlStructures::ProhibitMultipleSubscripts - forbid using the same subscript multiple times in a loop
AFFILIATION
This policy as a part of the Perl::Critic::PolicyBundle::SNEZ distribution.
DESCRIPTION
Conway suggests only extracting specific values of arrays and hashes in loops exactly once and assigning them to variables for later access. Not only does it make the code less cluttered with repeated lookups, it is also more efficient in many cases.
CONFIGURATION
This Policy is not configurable except for the standard options.
