Arc New Features

This seems pretty different to me than the use of single character operators in C-like languages. "odd+pr" has a completely different meaning than "odd + pr" (which might be 3 functions being passed into some other function). In the latter, "+" is the addition function. "odd+pr" reads more like a single token indicating a function. Kind of like the difference between morphology and syntax, where "(+ a b)" is a phrase and "odd+pr" a derived word.

So this dual level syntax is what I'm getting at. I know there is the expression/statement distinction in other languages, but this seems different. Perl sigils might be a closer idea, but those are more like case markers, I think. You can't use Perl sigils to combine multiple tokens into another token-ish thing, as far as I know.

Hope that made some sense.

The Rebol thing mentioned in another comment, by the way, does seem more like what I'm talking about.
