"If we made a secretarg for "the object the function is invoked on", then it's like every function in the language has it as a lexical parameter."

Hello dynamic variables!

"Is this close to what you have in mind?"

Sorta. The idea is close, but your way looks too verbose. I want it to be really short and simple, so having to define methods in a special way does not sound good to me. I want them to be plain-old functions.

I have an idea for what I'm going to do, and I think it'll work, because in ar, lexical variables always take precedence over dynamic variables, from what I can tell.

By the way, right now I only care about ar compatibility, since ar has nifty stuff like dynamic variables, which I've come to love. This not only should make the library shorter and easier to understand, but I honestly can't care much about compatibility, because my library kinda needs defcall, which isn't standardized[1] (and isn't even in Arc/3.1 at all)

* [1]: Or so I hear. I don't actually know.

"Hello dynamic variables!"

Secretargs happen to be implemented in terms of dynamic boxes. The benefit of secretargs is that you can always pass the default value just by making a normal function call; you don't risk propagating the existing dynamic value into the call. Whether that's important in this case is up to you. ^_^

Oh, and I don't think we can say anything's standardized in Arc at all. :-p The standards are just implicit assumptions around these parts.

Note: when I said "standardized" I meant in the "de facto standard" way. Arc has plenty of those. :P

I agree that Arc has essentially no de jure standards[1], and I think that's a good thing.

* [1] The closest thing would probably be whatever pg does, but that would only concern the question of what official Arc is; other implementations would be free to either follow official Arc, or branch off into a different Arc-like dialect.
