Cryptol has supported user-defined infix operators at the value level since version 2.2.5 (2015). We should also let users define infix type operators, so we can write things like this:

infixr 10 ~>
type a ~> b = [inf]a -> [inf]b

We should also allow infix type constraint definitions (see #400):

type constraint i < j = (j >= i + 1)
