( #3333=superdoc: print w/replies, xml ) Need Help??

Update: Scratch that, reap the post, call me a fool. I should have invoked perl with the -l switch. The behavior is consistent. I dinn' catch the string "bug!" just in front of the shell prompt.

Update: changed title

Dear fellow monks,

playing with prototypes for a future perl talk at $work, I stumbled over the following (perl v5.14.3):

# file sub fn($); fn("no bug."); sub fn (\@) { print while $_ = shift; } __END__ Prototype mismatch: sub main::fn ($) vs (\@) at line 6.

That's fine and expected.
However, if the parameter list @_ isn't altered via shift, the fatal error is turned into a warning:

# file sub fn($); fn("bug!"); sub fn (\@) { print $_,$/ for @_; } __END__ Prototype mismatch: sub main::fn ($) vs (\@) at line 6. bug!

Would you consider that a bug, and if so, is it worth reporting?

In reply to yet another prototype bug? (not, please ignore) by shmem
