Subject: several warnings and unoptimized translation of non-postfixderef array expression ($exe[0]) by PostfixDeref
This array element expression: $exe[0] results in a number of warnings (which can be very noisy in code which uses that a lot). The translated expression is also a bit costly (a map). % echo '$exe[0]' | perl -MBabble::Filter=::PostfixDeref -0777 -pe babble Use of uninitialized value $rest in string eq at /.../lib/site_perl/5.28.1/Babble/Plugin/PostfixDeref.pm line 62, <> chunk 1. Use of uninitialized value $sigil in concatenation (.) or string at /.../lib/site_perl/5.28.1/Babble/Plugin/PostfixDeref.pm line 63, <> chunk 1. Use of uninitialized value $rest in concatenation (.) or string at /.../lib/site_perl/5.28.1/Babble/Plugin/PostfixDeref.pm line 63, <> chunk 1. (map {$_}, $exe) Thanks, Diab

Oops, that's actually quite broken. I mistook the $ for a @. Updated subject to reflect that.
