Yeah, this proposal is actually just plain excellent, and the 
depths of what it enables go well beyond what the text of the 
document states.

It came out of an attempt to solve a real problem John and Andrei 
were facing, and they listened to what me and Steven had 
discussed previously. It brings type safety, tuple compatibility, 
CTFE *and* runtime flexibility, user extensibility, and rich 
metainfo about each use.

It is easy to make this compatible with normal strings, but also 
html templates, sql queries, gnu gettext, shell commands, even 
things like assert handlers and detailed exception construction 
that defers string construction to the end... the list goes on 
and on. And the implementation is easy too.

This is a proposal worthy of D.
