Can Perl's Template Toolkit warn on undefined values?

Question

Is there a way to make Perl\'s Template display warnings for all undefined values that I attempt to use the GET directive on (via [% %]) during T

Answer 1

Yes. If you pass the DEBUG option to Template->new, TT will warn you about undefined values.
