"Go to definitions" with templates

[Volker-Weissmann]

I (sadly) have a lot of code that looks like this:

template<class C>
void func(C arg) {
	arg.member();
}

obviously ccls cannot find the definition of member(). Is it possible to have ccls (or similar software) give me a list of methods called member, that are methods of a class that is used to instantiate func?

I guess this quickly becomes really complicated, see clangd/clangd#493.
At the very least you need global analysis to find all instantiations. And then implement something like Typescript's union types.
