; next the general case
;;; 6 kinds of errors:
;;; string is either:
;;; lex-non-string, run-non-string, lex-string, valid
;;; index is either:
;;; lex-invalid, runtime-non-fixnum, runtime-above, runtime-below, valid
;;; char is either:
;;; lex-invalid, runtime-non-char, valid.
;;; that's 4x5x3 = 60 tests!
;;; If we skip over the lexical string check, (since I don't do it),
;;; we have: 2x5x3 = 30 tests.
