(fixed some ugly formatting)
From perl -V on my system: "This is perl, v5.6.0 built for MSWin32-x86-multi-thread".
And from my man pages:
exists EXPR
... (EDIT: stuff about hash, then)
Given an expression that specifies the name of a subroutine,
returns true if the specified subroutine has ever been declared,
even if it is undefined. Mentioning a subroutine name for
exists or defined does not count as declaring it.
print "Exists\n" if exists &subroutine;
print "Defined\n" if defined &subroutine;
Maybe you have a different version of perl? Or maybe this is explicitly a win32 thing? I don't know myself. But I do know the code works on my machine :)
AHA! it's an activestate thing at least:
