1. makeReadsPrec :: Name -> Q Exp

   deriving-compat	Text.Read.Deriving

   Generates a lambda expression which behaves like readsPrec (without requiring a Read instance).

2. makeReadsPrec1 :: Name -> Q Exp

   deriving-compat	Text.Read.Deriving

   Generates a lambda expression which behaves like readsPrec1 (without requiring a Read1 instance).

3. makeReadsPrec2 :: Name -> Q Exp

   deriving-compat	Text.Read.Deriving

   Generates a lambda expression which behaves like readsPrec2 (without requiring a Read2 instance). This function is not available with transformers-0.4.

4. useReadPrec :: ReadOptions -> Bool

   deriving-compat	Text.Read.Deriving

   If True:

   • Derived Read instances will implement readPrec, not readsPrec, and will provide a default implementation of readListPrec in terms of readPrec.
   • If built against base-4.10 or later, derived Read1/Read2 instances will implement liftReadPrec/liftReadPrec2, not liftReadsPrec/liftReadsPrec2, and will provide default implementations of liftReadListPrec/liftReadListPrec2 in terms of liftReadPrec/liftReadPrec2. If built against an earlier version of base, derived Read1/Read2 instances are not affected, so they will act as if this flag were False.
   If False:
   • Derived Read instances will implement readsPrec.
   • Derived Read1 instances will implement readsPrec1 (if built against transformers-0.4) or liftReadsPrec (otherwise). If not built against transformers-0.4, derived Read2 instances will implement liftReadsPrec2.
   It's generally a good idea to enable this option, since readPrec and friends are more efficient than readsPrec and friends, since the former use the efficient ReadPrec parser datatype while the latter use the slower, list-based ReadS type.

5. defaultReadOptions :: ReadOptions

   deriving-compat	Text.Read.Deriving.Internal

   ReadOptions that favor readPrec over readsPrec.

6. deriveRead :: Name -> Q [Dec]

   deriving-compat	Text.Read.Deriving.Internal

   Generates a Read instance declaration for the given data type or data family instance.

7. deriveRead1 :: Name -> Q [Dec]

   deriving-compat	Text.Read.Deriving.Internal

   Generates a Read1 instance declaration for the given data type or data family instance.

8. deriveRead1Options :: ReadOptions -> Name -> Q [Dec]

   deriving-compat	Text.Read.Deriving.Internal

   Like deriveRead1, but takes a ReadOptions argument.

9. deriveRead2 :: Name -> Q [Dec]

   deriving-compat	Text.Read.Deriving.Internal

   Generates a Read2 instance declaration for the given data type or data family instance. This function is not available with transformers-0.4.

10. deriveRead2Options :: ReadOptions -> Name -> Q [Dec]

    deriving-compat	Text.Read.Deriving.Internal

    Like deriveRead2, but takes a ReadOptions argument. This function is not available with transformers-0.4.
