There is a way to capture the return type/parameters of a templated

Yes, i know that the template don´t have any type until explicitly coded

Or another solution like getting the string function declaration will be
"void add(T)(T t)"

Like what happens with:

void other_add(int x){}
writeln( typeof(__traits(getMember, Module, "other_add")).stringof );
//output: void(int x)

There are several related options in std.traits. What exactly are you trying to achieve? Perhaps there is a better way.


I´m working on a Lua binding for D.
One of my ideas is to try to make automatic binding for structs, even if some method have templated arguments. My idea is to at least try to bind templated functions with basic types automatically (in the example, bind then add!int, add!float, add!string etc..)

I tried arity!add which should resolve my problem too, but did´nt compile too.

So for now my idea is to brute force the numbers of arguments with 'compiles' trait or trying to get the sourcecode somehow.
