Implement universal types?

Hello,

Just joined ML after reading up on prothon and
prototype-based programming. I'm a long time python
user but I decided to join because this new language
looks quite exciting.

There is a PEP to add/replace long, int, and float,
long with a single decimal type with bounded precision
and floating point. 

http://www.python.org/peps/pep-0327.html

Even though from a language implementation point of
view it might be tough, I think that from a prothon
user point of view, a single decimal type would be
great idea - together with the . (what about complex
type?)

Also, the question of text / strings. Better to
implement unicode from the start? (like java)
