Always false float comparisons

One thing that's immutably true about computer floating point is that it does 
not make intuitive sense if your intuition is based on mathematics. It's a 
hopeless cause trying to bash it into 'making sense'. It's something one has to 
simply take the time and learn.

This reminds me of all the discussions around trying to hide the fact that D 
strings are UTF-8 code units. The ultimate outcome of trying to make it "make 
sense" was the utter disaster of autodecoding.

Yes, of course. I believe error messages should suggest corrective action.
