and from the recent discussion it seems that stack has slightly different
goals: One stack.yaml can reference vaious cabal package descriptions,
something I've never use until now, because I wasn''t even aware that it is
possible. :-). So apart from the different surface syntax, there seems to
be more fundamental differences.

can repetitive stuff like the tons of almost-copy-n-paste in
https://github.com/haskell-opengl/GLUT/blob/master/GLUT.cabal be avoided?
This has nothing to do with syntax, more with abstraction facilities and
semantics: If we just switch to JSON or YAML, GLUT.cabal would as
repetitive as before, only in a different surface syntax.
