( #3333=superdoc: print w/ replies, xml ) Need Help??
I've been looking forward to A12 for a while and I don't think I'm disappointed. - There's plently of stuff I haven't grokked yet - but the stuff I do really excites me.
The only concern I have at the moment, is the many references to compiler optimizations, as below...

It might be objected that this will slow down the parameter binding algorithm for all methods favored with an implicit *%_, but I would argue that the binding code doesn't have to do anything till it sees a named parameter it doesn't recognize, and then it can figure out whether the method even references %_, and if not, simply throw the unrecognized argument away instead of constructing a %_ that won't be used. And most of this "figuring out" can be done at compile time.
Will Perl6 not still have eval? - Will this not have an impact on any compiler optimizations that I don't explicitly ask for?
e.g. What if the above method's 'extra' arguments are thrown away, but auto-genereated code inside an eval tries to reference it? How can the compiler ever be sure enough to make that optimization except in the most trivial example?
method foo { return 1 }
However, I don't know a thing about compilers, so I don't know what I'm talking about - just giving you feedback on what I'm "troubled by" ;)
