It calculates least fixed points.  `fix' is as good a name as any.

`limit' is terrible; the argument to fix, a -> a, is neither a sequence
nor diagram nor net type, and hence its values don't have limits...


PS Yes, I know fix a = sup_{i=0}^inf f^i(bot).  That sequence is rather
different than the input function...
