bind :: Monad m => (a -> m b) -> m a -> m b

I like this argument order better, because it shows how (a -> m b) gets
lifted into (m a -> m b). If we only get one word, and we have to choose
between naming (>>=) and (=<<), I'd choose the latter for this reason.

I don't care what the name is, but having an alphabetic name for most
operators would be nice. Haskell's custom operators are a turn-off for
several people I know. I don't think Haskell the language should push
operators onto people that don't want to use them. Nor should the burden be
on them to create an alias.

If I could go back and redesign Haskell, I'd make it so that operators
could only be defined as synonyms of alphabetically-named functions.
