I'm trying to debug stuff, so I want to add verbose logging

static a = S!int(); // bah

I guess users can call this code from any context, but when i'd also like to see the log output for debugging purposes. Is there a way around this?

Can I maybe only do a writeln in a non compile-time context?

How about debug [1]?

struct S()T {
    this() {
        debug { writeln("Created..."); }
    }
}

and compile with the debug flag. You can also specify a debug identifier or level.
