It seems D won't replace

This also seems like a bug in D because manifest constants
used as sole arguments to ctfe'able functions should be
replaced by the function result.
CTFE is explicit. You could make it `encrypt!"encrypted at
compile-time"`. Then let encrypt return some struct, which
decrypts at runtime.
? I thought CTFE was for normal functions?
I guess I was mistaken ;/
CTFE is triggered when the result is immediately required to be a
compile-time constant.
auto x = anyFunc("fdsa"); // anyFunc executed at runtime
static x = anyFunc("fdsa"); // anyFunc executed at compile time
enum x = anyFunc("fdsa"); // ditto
template value argument are also of course required to be
compile-time constants, so passing the immediate result of a
function call to a template will cause the function to be
evaluated at compile time.
The way I think about it is that functions are (attempted to be)
executed at ctfe on an as-needed basis.
