I'd recommend implementing your own based on `read-from-string'.

unfortunately, there's no hook (standard or otherwise, to my knowledge)
into the decision process after a string of characters has been read as a
token (of constituent characters), so it's hard to bail out before it is
interpreted as a symbol if it is not a number, so you might want to check
the set of characters that this string consists of before you call
