You can kinda achieve this with a zero arg template today:

void func()() {
      static assert(0); // only triggered if actually called
}

I use this for a lot of things including optional dependencies 
too.

`dmd -i main.d` would only trigger static assert failures in 
modules actually imported, so that can work for a while too, then 
`dmd *.d` to build all.

But none of these offer compelling advantages over `grep -r 
"NotYetImplemented"`
