Collect the arguments of all the function calls at a compile time in the whole program.

[BoQsc]

Let's say I have this example program.
I want to get the arguments of all the `some_function();` in the 
whole program.
**Even if the scope of the function call is never executed.** 
(Ex. due to IF statement being negative.)

I tried to use `__traits` but it seems to not gather any 
information about function calls.
Or I'm missing something.


```
import std.stdio;
import std.traits;


void some_function(string argument){}


void main(){
   some_function("someargument1");
   some_function("someargument2");

   if (false){
     some_function("someargument3");
   }


/* __traits allMembers does not print function calls.
  I tried to use allMembers of __traits, but it does not contain 
the function calls.
  Only the functions definitions/declarations inside a module.
*/
foreach(memberss; __traits(allMembers, mixin(__MODULE__))){
		write(" ", isSomeFunction!(mixin(memberss)));
		writeln(" \t", fullyQualifiedName!(mixin(memberss)));
		
	}

```

```
