Agreed here.

I think that the absence of any portable way to implement correct
hash tables on inexact numbers is in fact a game-stopper.  It is
an indication that the standard is too flawed to release.

A flaw or missing feature that someone can code around in a portable
way is one thing; fundamentally lacking the primitives to code
something is a more serious matter.
