?  gmpy is a wrapper over the GMP library, which in turn is
implemented in C or assembler.  Don't know exactly what you
mean by "a pure Python type", but if you mean a type entirely
coded in Python, gmpy doesn't have any, and I'd appreciate it
if you could point out to me what part of the docs misleadingly
gave that impression, thanks.

I don't think LinearAlgebra.inverse can invert any matrix with
typecode 'O', though I may be wrong on that -- but if I'm not
wrong, then there's rigorously nothing that gmpy can do about it.

Is that what you mean?
