Exactly. Snippets from S06:
Multimethod and multisub invocants are specified

Invocants are the first few *positional* arguments used for a function
call, but certainly not arguments inside some kind of flattening

Imagine you have instead of ...
'foo'( args :flat )
end
.end
.sub
You folks took me too literally :) I meant: Given a system without
pugs/parrot/haskell (I assume perl5 is required), what are the things you
need to install so that you can say
perl6 -e say 'hello world'
i.e.
tar xf ghc.tar.gz
./configure
make
make install
tar xf parrot.tar.gz
make
make test

That's unfortunate. I thought :flat was like the splatty behavior in

Yes, exactly. I thought :flat and :slurpy were symmetric.

In this example, $x, $y, and $z are positional args. I would expect C
foo(1,2,3) and C foo([,[EMAIL PROTECTED]) to be identical calls --

From S06:

To flatten before the list is even passed into the subroutine, use the eager
list operator:

In an effort to keep the source tree nice and tidy, I'd like to
propose that we remove the following languages from the Parrot source

Some are new, some are reworded, some are from recent posts. Thanks to those

Yep, I knew what you meant! I'm in the process of writing this up
right now, assuming I can finish compiling Haskell sometime this week
(it ain't exactly a fast compile, hrmph).

Hmm, seems that another call signature bit is in order then, which
looks into flattening arrays for multi dispatch purposes.

I'm not sure it's just multi-dispatch; it looks like all signature checking.
