Comment(by zimmerma):
I find {{{isinstance(1.2, sage.rings.real_mpfr.RealNumber)}}} not
satisfying for three reasons:
(1) it is much too long, compare say {{{isinstance(17, Integer)}}}
(2) it explicitly refers to the underlying implementation and the MPFR
component: this should be
hidden from the user
(3) that underlying implementation may change in the future, which will
break some code using
{{{sage.rings.real_mpfr.RealNumber}}}
Thus we need a shortcut like "Integer" for real numbers.
