On a more productive note: in Racket code I define and use 'implies' a lot,
often conjoined, for predicates. It's mainly of declarative value, which is
perhaps why it's uncommon in implementation despite how common it is in
specification. And for boolean expressions in general I also use 'neither'.
Are these something that others [would] use and so could be added to Racket's
library?
Seems to me adding implies, nand, and nor to racket/bool is a good idea.
Let me know if you disagree (and if you disagree after I've already
committed, it is a simple thing to drop the commit or change it).
I've occasionally written my own `implies', but never make it shortcut
like `and' and `or'. Speaking of which, would it handle more than two
arguments? One? Zero? What kind of associativity would be appropriate?
Bwahaha.
