minor problems to fix

- context for recursive expansion (maybe save context in the
  dictionary in the first place?)

- staaplc

But first something more inspiring.  Abstracting some of the parser
words into a simpler syntax.  The CPS and explicit CDR on the stream
makes it hard to read.

-> ok, but not many chances to use it..
