Has there been any discussion of providing support for syntax extension in Perl 6? I know some things are possible in Perl 5, like Switch, but it seems hard to implement and dangerous.
I know Perl 6 has a Switch statement, but it'd be cool if there was support for a powerful integrated macro processor that would allow things like Switch to be implemented conveniently.
I know, I know, feature creep, untried, Second System effect, hard to integrate macro expansion with debuggers in a way that's intuitive to use, focus on getting something out the door... I'm just thinking out loud.
