Thanks! I actually don't dislike many things about it. I do like the
brevity, and the explicit projection into subsets.
The only objections I currently see are these:
- I really dislike the heavy use of overloading. It's especially
confusing in the case of <index-of>. It's a tradeoff I don't know
how to resolve. How about you give on <index-of> and I give on
- It can't be used to define sets of things other than symbols, which
my previous proposal could. But I suppose a separate form could
handle that, and we don't need it for R6RS.
Cheers =8-} Mike
