in thread What is true and false in Perl?

Only in the context of perl -e, as when run from a script, generates the same error (Argument "0 but true" isn't a numeric in addition (+) at line #. Also, both still print 0. And in both cases the attempt to add the string to 0 is ignored.

    Not quite sure what you are saying, but neither is behavior different when run as a 'script' versus on the command line via -e, nor is the arithmetic operation 'ignored'.

    >cat use warnings; use strict; print 42 * '0 but true', "\n"; print 42 * '0 but zonk', "\n"; >perl 0 Argument "0 but zonk" isn't numeric in multiplication (*) at +line 5. 0

    Update: Verfied on ActiveState 5.8.9 and Strawberries 5.10.1, 5.12.3 and 5.14.2.
