Sommaire

NAME

Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument "substr" instead of writing "substr($foo, 2, 6) = $bar".

AFFILIATION

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

DESCRIPTION

Conway discourages the use of "substr()" as an lvalue, instead recommending that the 4-argument version of "substr()" be used instead. 
     substr($something, 1, 2) = $newvalue;     # not ok
     substr($something, 1, 2, $newvalue);      # ok

CONFIGURATION

This Policy is not configurable except for the standard options.
