In the recent push to implement all of Tcl's [expr] command, Tcl has
come to the point where it needs to understand Inf and NaN.
After a brief discussion on IRC, it seems like PMCs are the proper way
to handle this. Specifically, three new PMC types: NaN, Inf, and
NegInf. So here's what I'd like to do:
don't forget about negative-not-a-number, and the quiet (or signaling)
alternatives; you're not specific as to which behavior you expect from
these, so i can't be more specific as to which behavior you've failed
to represent. i won't speak to the solution, but i do want to point
out that the problem space includes numerous (though countable)
numeric error conditions.
