Ah I see now.

A pattern is starting to emerge. You're thinking about redefinition much harder than me. My approach so far has been: compiler warns of redefinition, I stop the presses and go figure out if it's a problem.

"If a macro is given keywords it doesn't recognize, are they just passed to it as symbols in its rest arg, or should it be treated the same way as a function?"

I hadn't considered that, but fwiw the current wart implementation simply strips out unrecognized keyword args and the values provided for them. Hmm, that's probably wrong.

My only point with 'late is to demonstrate a utility that needs a different implementation once keyword arguments are introduced to the language, and which may have no implementation at all if the keyword argument framework isn't comprehensive enough.

But yeah, I do think about redefinition a lot. ^^ Penknife's core library, when I get around to it, will be designed for people to be able to modify it, the way people do with arc.arc. I'm also trying to give it a module system that plays nicely with that kind of invasive coding style. It's for customizability's sake.
