> You should be able to do printf-style debugging in ANY pure function.

Do you mean something like this?

pure void foo() {
    debug { printf("foo"); }
}


And even giving the compiler an explicit debug{} tag that is tricky. In general
writing is a side effect. So if your programs output is the text it produces,
its output may change according to how much the compiler optimizes away pure
function calls.
