in reply to Re: Autoloading and anonymous subs
in thread Autoloading and anonymous subs

And it's always the main package:

package Foo; sub AUTOLOAD { __PACKAGE__ } print $foo->(); package main; sub AUTOLOAD { __PACKAGE__ } __END__ main

I just can't find the documentation for this behaviour.

    You are calling an undefined coderef. This coderef (which isn't, being just nothing, or not existing) has no association with any package, albeit the variable holding "that nothingness" (if nothing can be something) has. Now, how should perl resolve that sensibly? There's no package, there's no code, there's no sub. Hence the default package (main), and as last resort, AUTOLOAD.

    The documentation is implicit in perlsub, perlref, ...


    _($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                                  /\_¯/(q    /
    ----------------------------  \__(m.====·.(_("always off the crowd"))."·
    ");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
