Well, my problem is the following: to parse the the source code, give id to function implementations and to connect these id with calls of functions. The difficulty appears because of existing different functions with same names (function overloading). So using distinct-values() excludes overloaded functions.

Now I understand that most likely I was going in wrong way at all.

I wonder how would that look like? And, next.. What's the problem you
couldn't solve yet?
