I just thought that filter() could be evaluated at compile time too, as others function that I've used so far. Sometimes I don't know if a native function can be evaluated at compile time until I do enum x = func();
Yeah, it takes some getting used to what happens when and how these interact. I can recommend H. S. Teoh's writeup: https://wiki.dlang.org/User:Quickfur/Compile-time_vs._compile-time
if I want to have minimum runtime code to filter out immutable strings, the first one is better right?
Indeed. It generates the equivalent code to just writing the writeln()s you want, with no run-time overhead.
