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.

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

This Policy is not configurable except for the standard options.
