Whoah, that's scary. What are some examples of this happening? Does this mean it's unsafe to store Doubles in a Map?
It's unsafe to use them as a key ((Set a) being effectively (Map a ())), but that should be pretty obvious anyway given that (==) isn't reliable for Double. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
