Note that ANY call to the runtime cannot be be interpreted in CTFE (because
source code is not available). This bug, like bug 4021, is an enhancement
request.

The spec specifically says that .dup, .length, .keys, and .values are the only
built-in properties which are supported in CTFE. To support these others, they
would need to be (a) moved out of the runtime; or (b) special-cased in the
interpreter. And case (b) is not going to happen.


In 2.043, this gives the error message:

crash.d(38): Error: _adReverse cannot be interpreted at compile time, because
it
 has no available source code
crash.d(41): Error: cannot evaluate foo([1,2]) at compile time
crash.d(41): Error: cannot evaluate foo([1,2]) at compile time

which I think is slightly improved from before -- it at least explains that the
missing source code is the reason why it cannot work.
