Guess it's not allowed to keep discussing in the feedback thread 
so I have to copy it here.

alias I(T...) = T;
alias X(T...) = I!(interp!(T[0]), interp!(T[1]));

Sorry for being daft, I simply don't get it... there's no issue 
with applying map to a tuple of string literals...
X!("one","two")

Maybe you have to jump through some extra hoops, but in the 
common case, is more optimized if there are no superfluous 
template instances for every little string...
