The only workaround I have used for this is to turn a tuple into a compile-time "struct" to pass it to another template:

import std.metastrings;

// use whatever name you want, and add whatever 'member' aliases you need here
template Struct(V...){
	alias V Values;
}

template MyExample(alias Arr1,alias Arr2){
	pragma(msg,Format!("%s",Arr1.Values[0]));
	pragma(msg,Format!("%s",Arr2.Values[0]));
}

alias MyExample!(Struct!(1,2,3),Struct!("x","y","z")) Foobar;
