Just to clarify -- *all* versions work at CT; the static-foreach
will be unrolled at CT, and the mixin argument will be fully
evaluated at CT too. The only difference is in a) readability, b)
the `write` template instantiations (and potential re-use).

Using the std lib `write*` templates has a huge cost; for any
kind of /real/ programs, that care about performance at all, they
are better avoided. (But it probably doesn't matter if you already
heavily rely on GC and don't print much, other than that they add
tons of code to the executable)
