Yup that's my proposal:

Walter's proposal isn't bad, though mine is better :)

However I would tweak one thing about mine. Before I said "auto 
arg1 = 50; ". I'd actually change that now to `auto arg1 = () => 
50;` for more compile time / runtime mixing compatibility.

I might also steal the raw string thing from Javascript... and I 
actually kinda like the format string from Walter's proposal, 
though mine can actually do that too already by reading format 
stuff in CTFE right out of the string.
