Does Semantic support some kind of completion of arguments when writing function calls?

I believe this is one of the most important features of any IDE and my guess is that it shouldn't be too complicated to implement it CEDET.

We could probably "borrow" code from template/snippet libraries, for example yasnippet, for the argument navigation/modification part.
I like its in-place-navigation interface.

And the function signatures already exists in Semantic right?

What semantic-function do I use to iterate over these function arguments?

Thanks in advance,
