In GCC there is a way to (sometimes) do it, see the __builtin_constant_p here:

Time ago I have asked for something similar in D too, becaus
I think invoking a template to call the pure function (StaticEval!(Hash("foo"))
isn't much different from StaticHash!("foo"). You still have to explicitly know
whether you're dealing with a compile time constant or not. I'd really like to
figure out how to have Hash("foo") be static and Hash(vari

Walter has decided that he doesn't like the D compiler to arbitrary run at
compile time arbitrary long to run code. Th
Oh, I also wanted to mention that although ideally I'd be able to invoke the

I'm also worried about accidentally invoking the runtime version when I should
