For a compile-string that's statically fixed (i.e.,

transform the entire writefln call into a series of puts() and
formattedWrite() calls.
The take home point is that ctFmt would *also* parse the string
at compile time. The difference is that it creates a run-time
object, which still contains enough static information for a
powerful write, yet still some run-time info to be able to swap
them at runtime.
