Attached is a patch that prevents implicit conversions from mpq and
mpf to mpz. It might be a good idea to also disable conversions to
mpf, but I don't know, I need other opinions. Conversions to mpq sound
fine to me (no loss of information, although an mpf may generate a
I am not enough of a C++ type to know which conversions to make
implicitly, and how relevant this is for backwards compatibility.
Am I right to assume that this only affects source compatibility, or
does it somehow also affects binary compatibility? In the latter case,
we need to update the libtool solib numbers in the toplevel Makefile.am.
