Regarding `recursive-parser', note that this has nothing to do with
recursive parsing per se, but rather exists to simplify *syntactic*
recursion, i.e. referring to a parser before it has been defined. For
example:

  (define a*b
    (any-of (sequence (is #\a) (recursive-parser a*b))
            (is #\b)))

Without `recursive-parser' you would need to enclose the parser body
manually somehow. Regardless, the infinite recursion you're seeing is
due to your grammar, as megane says.

Best,

Evan
