But beware that Python doesn't really get this quite right:

    >>> (1+2j) * (3+4j)
    (-5+10j)

    >>> 1 + (2j*3) + 4j
    (1+10j)

    >>> 1+2j * 3+4j
    (1+10j)

That is, the '+' and '*' operators have their usual precedences. There
is no 'special' high-precedence operator for complex construction.

Also, the latest 'C' standard (C99?) has support for imaginary and
complex numbers, but I'm not sure of the lexing details...
