That's exactly what mine would do.

But at the same time, with mine, you could *also* do

snprintf(buffer.ptr, buffer.length, i"foo %bar".c.tupleof);


Check out a draft hacky 100% library implementation here:
http://arsdnet.net/inter.d

the compiler can do a slightly better job avoiding the copying of 
values (the library can too... but not if you also want all 
three: RT+CT compat, C function compat, and expressions in the 
interpolated string. It is a kinda pick any two. Unless I'm 
missing a cool trick. But the compiler can express more than the 
library.)
