[34S] Complex numbers

Hey that is an interesting comment. I myself tend to always remember what is in stack to seek for optimization... Also there is always the risk to stack 9 items - ok this is probably very unlikely but I wonder how you approach RPN with large stacks?

"useless" is may be going a bit far but I tend to see your point.
This being said I guess there is a similar flaw in between 15C and 34S. To enter a complex value in the 15C you would do:
1. Real value
2. ENTER
3. Imaginary part
4. (f) I
So basically until step 4 you used 2 stack entries pretty much like the 34s.
