Add option for obfuscation imports

[rominf]

I propose you to add possibility to obfuscate imports. So, instead of having:

from numpy import array
import re
...
array(...)
re.match(...)

we can have:

from numpy import array as σΣΕξ
import re as αβ
...
σΣΕξ(...)
αβ.match(...)

I think it's not hard to do, it will increase unreadability.

match is still readable. I think that monkey patching can help, but it can break some code:

import re as αβ
αβ.γx = αβ.match

This one will be an interesting technical challenge so I'm definitely going to try it!

I was just trying this, and it seems like this feature was already added...
