Comment (by goldfire):

 I agree in that I find the impedance mismatch between term-level `String`s
 and type-level `Symbol`s a little annoying. But, there's a fairly sensible
 workaround: use lists of one-character symbols. A little quasi-quoting to
 ease the syntactic pain and you can get fairly far.

 I would still rather, of course, built-in support.
