OK, that last discussion was productive, but I think we all (including
myself) overlooked the fact that the AUTOLOAD and AUTOSUB methods are
implied to have different calling conventions;
There is still an AUTOLOAD hook that behaves as in Perl 5.
The (AUTO*) routines are expected to return a

I also don't see the symmetry between AUTOLOAD and AUTOMETH. Two things
bother be about that: LOAD versus METH, while it should be SUB versus
METH, and that METHOD is abbreviated while in the method keyword it is
not. Either it should be abbreviated everywhere: meth foo { ... }, or

It's nicer to type, but I think that your preferred syntax means that
the AUTOLOAD sub itself has to call any loaded code, which can mean that it
has to fit arbit

I don't recall any clearl spec of Perl 6's AUTOLOAD. If there is
something I missed, say so and please do provide example code. Questions
like the one quoted tend to irritate me.

Maybe it should be passed a continuation too, then? Then it could
choose exactly what to do with it.

Hi,
"&kilobytes := &kilobyte;" will not work for you (try it), because you
have to declare the "variable" kilobytes - in the default strict mode.
But you can't say for ex. "my &kilobytes", if you want to export it.
So you say `our &kilobytes ::= &kilobyte` (or `:=`, you still haven't

Hi,

Perl is modeled on natural languages, but that doesn't mean it is one.
At its core, Perl is a limited, artificial language being explicitly
designed with certain goals. One of those goals is that it should be

András,
I think you have just discovered AUTOLOAD :-)
OTOH I don't know how the AUTOLOAD mechanism will work in Perl6 compared
to Perl5, or if it has been imlemented in Pugs (yet), but as far as I
remember, in Apocalypse 12 somewhere it says it will work the same(?) as
in Perl5, and what you
