Making the DIP work with printf wont make it work with all simple 
interfaces. So printf is not "a canary for simple interfaces". 
All it actually does is make it work with a very specific subset 
of "simple interfaces" at the expense of all others.

You solved the equations for one variable, but you still have 3 
unknowns.

I dont, I have a few custom wrapper functions for formatting 
floats, and i use writeln.

I dont like either proposal tbh.
