Hi Paul,
I'm nit experienced in Haskell, so I don't have a solution. But the
following keywords spring to mind:
Ignore the syntactic sugar and see if any of the alternative syntaxes are
more flexible
https://wiki.haskell.org/Case
Create a DSL.
Greetings,

Hello, Everyone!
As I understand "MultiCase" proposal was not approved, so my question is: is there alternatives to multi-case? I have code like:
case x of A a -> .. B b -> .. C c -> --same-- D c -> --same--
and I want to merge code of "C c" with "D c" branch. Anywhere, in general: is any alternatives to make "OR"s in patterns? I don't see how to do it with pattern guards, pattern synonyms, views extensions and don't see another related extensions.
Something like "(C|D) c -> ..."
