Simpel answer: the current code was already available for the reading of
typed constants. Only the implicit generation of the assignments was
needed. It took only 30 minutes to get it working.

I don't see the problem there is currently a clear distinction. In
statements you need to use := for assignment. And in declarations
(enums,default parameters, typed constants, initialized vars) you need to
use =.
