Has there been historical work done to investigate small integer optimization?

But implementing it with the current mpz type is "impossible".
I mean, one should break the current interface.
Currently, _mp_d is always a pointer AND it always point to a readable limb. Even if _mp_alloc is zero.

To implement the idea inside GMP one should choose:
 - break current interface, or
 - fully implement a new layer (not mpn, mpz, mpf, but... mpZ?).
