in this case it should ideally throw some error...

Further to Laurent_R's reply: If jabirahmed really wants to make these missteps into (fatal) errors rather than just having them generate nagging warnings, that can also be done. See perllexwarn. (Note that this control of fatality is lexical!)

>perl -wMstrict -le "print 4 + 'a'; ;; use warnings FATAL => 'numeric'; print 5 + 'b'; " Argument "a" isn't numeric in addition (+) at -e line 1. 4 Argument "b" isn't numeric in addition (+) at -e line 1. >perl -wMstrict -le "print 4 + 'a'; ;; use warnings FATAL => 'all'; print 5 + 'b'; " Argument "a" isn't numeric in addition (+) at -e line 1. 4 Argument "b" isn't numeric in addition (+) at -e line 1.

(Many Perlers favor escalating  'all' warnings to fatality. I tend to agree with this practice, especially for modules, both OO and non-OO. However, I must admit that such fatality can get annoying during debugging.)

    [ambrus]: thezip: is Activestate Perl usable for your scenario instead?
    [MidLifeXis]: Yeah, --notest is good, not sure I would do --force.
    [thezip]: It fails 2/10 tests in that group. What are the ramifications if I force it? What should I look for for?
    [thezip]: I've migrated from ActiveState to Strawberry. No going back...
    [thezip]: I'll try the --notest arg first when I get back from meetings (after lunch).
    [thezip]: Thanks guys for your comments! :-)
    [1nickt]: Quick survey: has anyone used or even heard of autobox?
    [Corion]: thezip: I would expect some (fancier?) numeric formatting to fail from these test failures
    [1nickt]: ( Sometimes when idle I browse remote corners of the code repo at $work ... usually this yields knowledge of projects to decline and coworkers to avoid ... )
    [LanX]: sure
