Perl::Critic::Policy::BuiltinFunctions::ProhibitLvalueSubstr - Use 4-argument substr instead of writing substr($foo, 2, 6) = $bar.
substr
substr($foo, 2, 6) = $bar
This Policy is part of the core Perl::Critic distribution.
Conway discourages the use of substr() as an lvalue, instead recommending that the 4-argument version of substr() be used instead.
substr()
substr($something, 1, 2) = $newvalue; # not ok substr($something, 1, 2, $newvalue); # ok
This Policy is not configurable except for the standard options.
