Remove complex and imaginary types?

Python has the literals too:

>>> complex(5)
(5+0j)
>>> (6 + 2j - 1 + 3j) / 3j
(1.6666666666666665-1.6666666666666665j)
>>> (complex(6, 2) - complex(1, 3)) / complex(0,3)
(-0.33333333333333331-1.6666666666666665j)


But maybe imaginary literals aren't necessary:

C++
complex<long double> a = 5;
complex<long double> b(0,7);
c = a + b + complex<long double>(0,7);

Current D:
creal a = 5;
ireal b = 7i;
c = a + b + 7i;

Alternative:
auto a = creal(5); // == creal(5,0)
auto b = ireal(7);
c = a + b + ireal(7);


C++:
c = (complex<double>(6,2) + complex<double>(-1,3)) / complex<double>(0,3);

Current D:
c = (6 + 2i - 1 + 3i) / 3i;

Alternative:
c = (creal(6,2) + cdouble(-1,3)) / idouble(3);
