digitalmars.D.learn - How to specify an exact template?

Here's the following line, among many others:

return &alphaBlend32bitMV!(ubyte);

This generates an error, as this function template matches two 
instances, but currently I don't know how to choose the one I 
need, other than write a local function, that looks a bit ugly.

Forgot to link the code example: https://github.com/ZILtoid1991/pixelperfectengine/blob/master/pixeperfectengine/src/PixelPerfectEngine/graphics/layers/base.d#L143

probably you can use https://dlang.org/spec/traits.html#getOverloads

I don't know how to use it with functions outside of structs/classes.

void foo() {} void foo(string i) {} static foreach(overload; __traits(getOverloads, mixin(__MODULE__), "foo")) pragma(msg, typeof(overload));

Well, it's quite complicated to do. I have to manually unwrap 
each and all function template, then pray for the compile-time 
optimization gods that they'll be inlined.

This is so annoying, that I might issue a DIP...
