I like arrow operators :-)
But I fear that it will be too easy to misread `=>` as greater than or
equal to, especially when skimming code.
Assuming that they need to be different arrows, how do you feel about
`->` for types and annotations, and `-->` for lambdas? Or `->>`?
JavaScript uses => for functions, and the confusion with ">=" doesn't
seem to be a major problem with it.
C# also uses "=>".
