On one hand I like such identifiers, but on the other there could be a
lot more.  Just looking at random things, I can see `π', `→' or `⇒'
(for `=>'), `≤', `≥', `…', `∞' and `-∞', `∊' (for `member'), `√', and
many more.  Maybe even `½', `¼', `¾', `-½' etc...

So how about some `racket/aliases' which is included in `racket' but
not in `racket/base' and adds some/all of these?
