Igor,

I think I don't undersand your point. What is the mathematical significance of an Array of size 0.2i?

least suprise for who?
For you it could be the least surprise.
For me, and for other people it would be a big surprise.
So, please give a better/different reasoning, why in a presence of
Complex numbers, a functions
which operating with Real numbers should change their behavior.

Integers are subset of Real set and Real is a subset of Complex, then
one could happily write:

Array new: 0.2i

and following your reasoning, the above is good way to write a code
and it should work well.
