RE: Puzzle: Warnings Golf

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.
