Thanks for the detailed input Simon.

If you're comparing one-liners though, it should be considered important
that you've explicitly turned on warnings in the latter with the -w
switch, but there's no option to enable/disable in Template. Without it,
of course:
$ perl -le 'print 1 + ""'
1
Similarly, compare and contrast:
$ perl -MTemplate -le 'Template->new->process(\q[[% blah %]])'
$ perl -le 'print $blah'
$ perl -wle 'print $blah'
Name "main::blah" used only once: possible typo at -e line 1.
Use of uninitialized value $blah in print at -e line 1.
or even:
$ perl -MTemplate -le 'Template->new->process(\q[[% BLOCK blah END;
BLOCK blah END; %]])'
$ perl -le 'sub blah {}; sub blah {}'
$ perl -wle 'sub blah {}; sub blah {}'
Subroutine blah redefined at -e line 1.
Why are some warnings expected and others not? Or am I being
disingenuous in this comparison? Are there any other perl warnings that
Template is expected to produce?

I suspect, without easily being able to test it, that the only issue is
that TT is acting differently between perl 5.8 and 5.10, and the version
of TT is irrelevant. Doesn't this make it a TT issue?
Cheers to everyone with their help, even if I have reached somewhat of a
stalemate and will probably end up with a hack on $SIG{'__WARN__'}
