>>> import gmpy
>>> gmpy.mpz(11)
mpz(11)
>>> gmpy.mpz('11',10)
mpz(11)
>>> gmpy.mpz(11,10)
Traceback (most recent call last):
File "<pyshell#38>", line 1, in <module>
gmpy.mpz(11,10)
TypeError: gmpy.mpz() with numeric argument needs exactly 1 argument
The mpz conversion takes two arguments if and only if s is a string,
else it takes 1 argument. So being non-empty is insufficient.
