{-# LANGUAGE GADTs              #-}

-- | Preprocess 'Agda.Syntax.Concrete.Declaration's, producing 'NiceDeclaration's.
--
--   * Attach fixity and syntax declarations to the definition they refer to.
--
--   * Distribute the following attributes to the individual definitions:
--       @abstract@,
--       @instance@,
--       @postulate@,
--       @primitive@,
--       @private@,
--       termination pragmas.
--
--   * Gather the function clauses belonging to one function definition.
--
--   * Expand ellipsis @...@ in function clauses following @with@.
--
--   * Infer mutual blocks.
--     A block starts when a lone signature is encountered, and ends when
--     all lone signatures have seen their definition.
--
--   * Handle interleaved mutual blocks.
--     In an `interleaved mutual' block we:
--     * leave the data and fun sigs in place
--     * classify signatures in `constructor' block based on their return type
--       and group them all as a data def at the position in the block where the
--       first constructor for the data sig in question occured
--     * classify fun clauses based on the declared function used and group them
--       all as a fundef at the position in the block where the first such fun
--       clause appeared
--
--   * Report basic well-formedness error,
--     when one of the above transformation fails.
--     When possible, errors should be deferred to the scope checking phase
--     (ConcreteToAbstract), where we are in the TCM and can produce more
--     informative error messages.

-- Andreas, 2012-11-17:
-- Mark computation as 'dirty' if there was a declaration that could be privatized.
-- If no privatization is taking place, we want to complain about 'UselessPrivate'.
--
-- Alternatively, we could only flag 'dirty' if a non-private thing was privatized.
-- Then, nested @private@s would sometimes also be complained about.
