 From there: "What it boils down to is this: if a function *can* be 
executed at compile time, it *will* be."

I think that gives the wrong impression. We regularly have newcomers in 
D.learn who expect CTFE to happen where it doesn't. They have a function 
call with all compile-time constants, and they expect it to be handled 
by CTFE. They think that the call *can* be evaluated at compile time, so 
it *will* be. But that's not how it works. CTFE only kicks in when the 
destination *requires* a compile-time constant.
