Description

Maybe this cat is out of the bag, but the fact that

Foo
    fooBar Text
    ...
deriving (Eq, Show, Read)

failed was surprising to me.

But then, I suppose it could be added without breaking anything.

Research direction

Start by locating the quasiquoting parser and its handling of deriving clauses; the issue does not name a file or test. Compare the accepted syntax with the Haskell-style example in the report, and consider the work complete when that form parses without breaking existing quasiquote behavior.
