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 0_but.pl use warnings; use strict; print 42 * '0 but true', "\n"; print 42 * '0 but zonk', "\n"; >perl 0_but.pl 0 Argument "0 but zonk" isn't numeric in multiplication () at 0_but.pl +line 5. 0` [download] Update:* Verfied on ActiveState 5.8.9 and Strawberries 5.10.1, 5.12.3 and 5.14.2.

>cat 0_but.pl
use warnings;
use strict;

print 42 * '0 but true', "\n";
print 42 * '0 but zonk', "\n";
