There is 0 effect on libgmpxx. Yes, it only affects source
compatibility. Some (very questionable) code will stop
compiling. Other than that, I don't think it can break anything, even
if linking together .o files from before and after the change.
Ok, should we allow any implicit conversions between GMP types? I think
C's type conversions are actively harmful, but C++ has done some cleanup
in this area with which I am only vaguely.
When dealing with "heavy" types like these, is it in the C++ spirit to
allow implicit conversions? Will we do any good by disallowing them?
