Hi Volker,
It is legal Haskell, but it isn't doing what you think. The patterns

right hand side expression of their alternative.
Since the a,b,c patterns are just variables they will match anything,
and the first alternative
Thanks for the bug report. I am investigating. In the meantime you
could change the declaration of ArgrC from a 'newtype' to an ordinary

Hope this helps
