For first try to implement RTTI, I create a plugin to visit AST nodes
and extract functions and classes methods info to generate a header file
based on AST nodes, This header contain a map from a function/method
signature in string to pointer of that.

To complete my idea , I need help to solve two problem : 

1- How to get pointer of overloaded methods and functions ?

An example:

template<typename T>
T sum(T a,T b) {
	return a + b;

int main(int argc, char const *argv[])
	return 0;

function extraction result is :

main (int argc, const char ** argv )
sum (int a, int b )
sum (double a, double b )

2- If a project contain more than one file how to generate a header for
all files ?
