Given the way complex numbers interact with floats generally,
returning a complex number with no imaginary component as a floating
point value seems legitimate and the checks in cmath overly strict.
Otherwise you would get redundancy like:
 def __complex__(self):
 return complex(value)
or
 def __complex__(self):
 return value + 0j
More importantly, relaxing the checks in cmath is backwards
compatible. while tightening up the checks in complex_new is not.
Cheers,
Nick.
