I think the point here is that it's not worth killing the golden 
goose just to have printf work easily - I personally think a 
solution is obviously possible even if not through this DIP.

Ergonomically doing code generation with format specifiers is 
just really really ugly and brittle. I feel similarly with printf 
although I still use it as writeln compiles to a remarkable 
amount of machine code.

One thing that's just struck me is that with move semantics this 
could have a bunch of potential GC usage eliminated for 
relatively little cost by using some structs in the right place.
