Hi Joseph.
I agree wholeheartedly. Perl is already very flexible in the
DWIM department: it will allow both text concatenation and
arithmetic increment on an undefined value. I have always
been grateful for the, 'Are you sure you mean this?' that
'use warnings' gives. (I just wish that 'no uninitialised'
was also valid).
