But it works only for array.

This feature will be really awesome and could be go into std.traits

Check 'opDispatch' and 'alias this'.

 Check 'opDispatch' and 'alias this'.

alias this is not the answer as it forward all, i fyo want select for
this member forwad this method and for another this one  ...

opDispaytch is not really easy to use for this. my first code do this in
1 line and it is easy to understand hat it do. In 1 line i forward 3
method to a member. This save time, code and bug.

So what's the problem with opDispatch?

By the way, don't do things like mixin(SomeTypeArgument.stringof) - it 
will not work in every case (name conflicts, nested structs/classes 
etc.) and it's unnecessary conversion to string and back to code. So it 
wasn't a good idea to change dav1d's variant this way.

You can just mixin an opDispatch function, like (not tested, only works for
functions)

    mixin template Forward(alias member, s...) {
        auto opDispatch(string name, T...)(T args) {
            static assert(canFind(s, name));
            return mixin("member." ~ name ~ "(args)");
        }
    }

or use a foreach over 's' and mixin the function/member definitions for
each name.
