Don't forget a !~ b, a <~ b, and a >~ b, and the associated __sim__, 
__nsim__, __ltsim__, and __gtsim__ slots.

I'm not at all sure how serious I am right now. It's late, and I have 
fuzzy recollections of how those kinds of things might have been nice in 
some past numerical code.

And then =~ and !~ could be defined for strings and do regular 
expression matching! Woo! More operators! With pronouns!
