I haven't been following the whole thread. How about something like this: X:\>perl -e "$a.a"
X:\>perl -we "$a.a" Unquoted string "a" may clash with future reserved word at -e line 1. Useless use of concatenation (.) or string in void context at -e line 1. Name "main::a" used only once: possible typo at -e line 1. Use of uninitialized value in concatenation (.) or string at -e line 1. Four warnings for four bytes: 1.0 ratio.
