What is "current" in Python or in any other general purpose programming
language? 
A: nonsense, I guess :-)

Note that even Matlab, that is widely used among engineers, uses "i" for
imaginary unit by default ("j" is an alias to "i").

That would be great, I think. Maybe in Py3K?

Though I suspect that there are still more engineers than
mathematicians/physists among Python users which makes the change 
1,1j -> 1,1i,1j,1k very difficult, right?
