Are you sure you got what I meant?
I want to compile the variable references away at compile
time, resulting in an ordinary format string.
This string is wraped by the runtime _(), and
the result is then interpolated with a dict.

Compile time does no interpolation but a translation
of the string into a different one, which is interpolated
at runtime.
