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
