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, ...

    --shmem

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

[marto]: so I have to work Saturday, which is good and bad. Bad in the sense that I have to be hear early :( Good in that I am here only as support for another client project, so I get to spend the day working on my personal 'ToDo' list, without the kids :P
[Corion]: marto: Ooof - but yes, being there as only second level support or third level support is good and if you have enough things that you can work on, it won't be a wasted (if paid) day
[marto]: I've opted for a day off later on, rather than pay. I only have to do about 45 mins work for the client, but do need to hang around
[Corion]: marto: Even better ;)
[marto]: and I'm off next week1
[Corion]: Whee! ;)
[Corion]: I was away last week already, so I know how good a week off is ;))
