Changes since v2:
  * Add some additional tests, based on actual uncaught exceptions
    I saw while using pattern groups in an ARM32 conversion.
  * Allow negative numbers in field=number.
  * Push extraction functions into the namespace of the decoder.

I'll probably give a PR for this on the weekend.
