it's only a GNU standard. btw i'm thinking about the possibility to mark
some methods as deprecated with an associated explanatory string.

This would be nice to develop, so you can mark a method as deprecated, and
all the times you call it the compiler will show you the 'error message':

[Deprecated (reason="foo() method has been deprecated, please use bar()")]
public void foo() {
        ...
}


or something like that :) what do you think?

it has nothing to do with the exp2 problem, but maybe we should warn or alias
exp2(x) as pow(2,x) that performs the same operation...so a tip like that can
be added into the vapi as [Deprecated] or [Tip] or whatever else, to let this
decission relay on the developer.
