[racket-dev] egal?

Short message: is there any chance of getting egal and egal hashes any time soon?

Longer message: I have a situation where I key my hashes with immutable structs, but something they contain has a box that later is updated and never changed. I'd really like for the struct value before the set-box! to be keyed to and positively compare to the value after this set-box! happens. Otherwise I have to do something abstraction-breaking to separate these boxes from the structures which would likely introduce more overhead (yet another hash lookup).

I'm going to look into just hacking egal in myself, but want to know what the other devs know about this.
Thanks,
-Ian
