Subject: Re: [PHP-DEV] [RFC] Importing namespaced functions
From: igor@wiedler.ch (Igor Wiedler)

I was about to make the same point as Johannes. Trying all possible =
variants in the autoloader is simply too slow (and in fact the main =
reason why we don't have function autoloading). On the flip-side, the =
current proposal would allow adding function autoloading more easily in =
the future.

Another note: To address the issue in a different way, some sort of =
syntax for importing multiple names would be nice. Something like:

    from foo use bar, baz;

But that is way out of scope, and should be done as a separate proposal.

Regards,

Igor
