Or if it is known to be CTFE'd

Just a warning, its a one time use only for both.
No other way to do it.
That's ... unfortunate.
Some search of the forum led me to some [decade plus old
discussion](https://forum.dlang.org/post/j1n1m2$24p0$1...@digitalmars.com) of a possible CTFE writeln function that would be a no-op at runtime, which to my surprise led me to find [core_builtins.__ctfeWrite](https://dlang.org/phobos/core_builtins.html#.__ctfeWrite) but when I tried it out, it compiled yet output no text to the console. Given your remarks I suppose I should have expected this.
