Hi.

When using pointers to functions with bind, the particular function doesn't play a part in the return value's type of bind. That is

void func1(); void func2();

typeid(boost::bind(&func1)) == typeid(boost::bind(&func1)) // this is true

I've made some progress. What I have now looks like:

template struct nontypeadapt;

template struct nontypeadapt { typedef Ret result_type; Ret operator() () { return func(); } };

then

typeid(boost::bind(nontypeadapt())) != typeid(boost::bind(nontypeadapt()))

However, the signature has to be given at the call site, it's repetitive to define all specializations of nontypeadapt, and it brings more forwarding problems of it's own. Any ideas?

I think you can only pass functions with external linkage as parameters to templates, which I think it makes it unusable...
