On the other hand this D program prints just

In a modern statically typed language I'd like such code to give a
compile-time error.
Actually this is good because it allows to customize the format string
to print only a subset of available information (I've actually used this).
why is there always a tiny need for such tricky stuff - isn't that only
usefull in very rare cases
or better said - could then someone add a description to writefln why
there is a need that writefln can "handle" more values then asked in the
format-string - maybe with an example that realy shows the usefullness
of this feature - and why an simple enum + if/else can't handle this
also very elegant
