Need Help??

in reply to Re^2: Detect undefined subroutines
in thread Detect undefined subroutines

Interesting idea, but it doesn't seem to work.

tilly@(none):~$ perl -ce 'use strict; *foo->()'
-e syntax OK
tilly@(none):~$ perl -e 'use strict; *foo->()'
Undefined subroutine &main::foo called at -e line 1.

Tested with Perl 5.8.4.

UPDATE I see, my oversight.

You need to turn on warning to see them...

    $ perl -Mstrict -cwe '*foo->()'
    Name "main::foo" used only once: possible typo at -e line 1.
    -e syntax OK

    $ perl -Mstrict -we '*foo->()'
    Name "main::foo" used only once: possible typo at -e line 1.
    Undefined subroutine &main::foo called at -e line 1.
