So, here is the new version of patch that contains modifications we've
discussed, namely:

* store oids of `parse`, `fetch` and `assign` functions

* introduce dependencies from a data type

* as a side effect of previous two I also eliminated some unnecessary
arguments
  in `parse` function.

I'm going to make few more improvements, but in the meantime I hope we can
continue to review the patch.
