The idea for the convenience operator is discussed on the DIP 
1027 thread [1] by Paul Backus (though he uses @ and I'm a bit 
more sympathetic to your #). The way he describes it is just a 
simple re-write of
writeln(@interp!"The number ${num} doubled is ${num * 2}!"));
writeln(mixin(interp!"The number ${num} doubled is ${num * 2}!"));

I find it an interesting idea, but wonder what the consequences 
of this are more generally.
