Luckily, {-# OPTIONS -fwarn-unused-binds #-} saves me from searching for the formal spec...

To your amusement, I found the following in the Agda source:

abstractToConcreteCtx :: ToConcrete a c => Precedence -> a -> TCM c
abstractToConcreteCtx ctx x = do
   scope <- getScope
   let scope' = scope { scopePrecedence = ctx }
   return $ abstractToConcrete (makeEnv scope') x
   where
     scope = (currentScope defaultEnv) { scopePrecedence = ctx }

I am surprised this is a legal form of shadowing.  To understand which
definition of 'scope' shadows the other, I have to consult the formal
definition of Haskell.

But I studied computer science to *not* become a lawyer!!
