Yes, that's exactly what I'm asking. Note that this is something 
D *already* does when it provides wrappers like `writefln` as 
alternatives to C functions like `printf`, so in practice, it 
should not require any new work to be done.

Keep in mind that any argument list you could generate using my 
or DIP 1027's interpolated strings is also an argument list you 
could have written by hand. So if a function is error-prone to 
call with string interpolation, chances are it's also error-prone 
to call without it.
