The question is not very precise.  I don't know what you mean by analyse,
nor what you mean by interfaces, nor what you mean by useful.  You can
write things like:

f(...,T i,...) { ... }
where T is a type and i is an identifier

or

f(...,p,...) { ... }
where p is a parameter

or

f(ps,p,...) { ... }
where ps is a parameter list and p is a parameter.

In declaratin a parameter list, you can also say;

parameter list[n] ps;

and then n is the number of parameters that are matched.
