Re: Perl 6's for() signature

[Damian Conway]

FWIW, we're aware of the problem.

I posed this very question to Larry a few months back, when I was writing E6.
We're still mulling over the correct answer. The last thought on the problem 
that Larry's shared with me was that there may need to be a special case for 
allowing a single &block parameter after the slurpy (which would then be 
popped off the parsed arg list before slurpification).

I don't think either Larry or I thinks that's ideal, so we'll probably keep 
working towards a better (more general) solution to the problem.
