Sounds good.  I generally agree with Vladimir about reusing
c_value_of_variable, however.

I believe it is as simple as:
  - Passing a struct value *.
  - Always returning NULL if there is no value, instead of doing
    the struct and array special cases first.
  - Using value_type to get the type code and the number of children.
  - Probably calling value_fetch_lazy first when passing it the new
    value, to avoid the assertions.

Let me know if you want me to try that myself.
