1. It can't be typed easily.

2. It can look like an n.

3. Single-character identifiers should not be promoted, especially with
   a global scope.

Mathematics and physics have run into trouble with single-character
identifiers already. They have run out of letters and have had to reuse
them. Programmers used to have the same problem until they realized it's
ok to use descriptive names.

Just say,

    >>> import cmath
    >>> cmath.e ** (1j * cmath.pi) + 1
