Sorry I wasn't clear about this. Here's what I had in mind:
1. Do some numerical calculations to prove a HOL4 theorem:
|- P[bit1,bit2]
2. When exporting such a theorem, first prove a theorem of the following form:
|- P[bit1,bit2] = P'[bit0,bit1]
3. Export the theorem
|- P'[bit0,bit1]
That way the numerical calculations wouldn't have to be reproved;
there would just be a "post-processing phase" converting between
different representations of numerals.
Cheers,
Joe
