Could you please explain?
I can't tell you why that is. But you can easily test it. Define a
function "_" in one Module.pm and you can call it without any
declaration from AnotherModule.pm.
In C, "_" is usually something like
#define _(arg) dgettext (DOMAINNAME, arg)
This allows libraries to use independent message catalogs. With a
global function, you cannot achieve this. Locale::TextDomain therefore
uses a double underscore as the default shortcut function.
Besides, "_" is also a magic file handle that caches the information
from the last call to stat() or lstat(). See the pod for File::Find.

Guido
