For ad-hoc temporary debugging usually a local wrapper

   @noinline writeln(A...)(A a) {
      import std.stdio;
      std.stdio.writeln(a);
   }

[the reason for @noinline is to not disturb the caller]
This is where the `print` function would be useful. It
could even be made to work at CT (w/ compiler help; this
has been a often requested feature).

For programs that output one or few text lines to stdout
(results, status updates etc) - `printf` -- it's already
there in libc anyway, so zero-cost and GC-free.

For everything else - the C/Posix functions.
