where is this documented?
That was in a "I think" sentence. Now that I looked a bit more, I don't
find it... Well, you can't call any mpq function that reads that mpq_t,
but we don't say you can't write to that mpq_t.
In mpfr_set_q we use the fact that the user can set q to 1/0
for example to represent +Inf.
I didn't remember that MPFR did that, but I did remember that some people
did that. I'll count it as a vote for Marco's patch.
