Using RT, I have to use strings

[[`string`, `0`], ...]

when it would be much better to use

[[string, 0], ...]

Ideally it wouldn't add so much overhead that it defeats the 
purpose.

You can make a template that doesn't expand the sequence automatically, 
and then make a sequence of those:

----
template Box(stuff ...) { alias contents = stuff; }
import std.meta: AliasSeq;
alias s = AliasSeq!(Box!(string, 0), Box!(int, 42));
----

Instead of `s[0][0]`, you'd have to write `s[0].contents[0]`. Don't know 
if that's too much overhead.
