What I ment was if your functions/procedures need to return new types,
which will be returned in multiple others extension modules, the other
modules does need to recompiled, doesn't it?  I mean how could C system use
something without proper interface? Sure I could include all header of
other previous extension modules in my new modules but still many
extension modules need to recompiled if I something in early make modules
is changed.
With C++ I could simple make an interface and changing implementions of
memberfunctions (aka methods) without need for recompilation of other
modules.

Furthermore I would like to make scripting language which is more based on
events and is more restricted than python. Yet making methods internally
with classes sound cool for speed - but it does spend huge amounts of
memory.

Hmm, I'll check out his work
