------------------------------------------------------------------------ -- Release notes for Agda 2 version 2.2.4 ------------------------------------------------------------------------ Important changes since 2.2.2: * Change to the semantics of "open import" and "open module". The declaration open import M <using/hiding/renaming> now translates to import A open A <using/hiding/renaming> instead of import A <using/hiding/renaming> open A. The same translation is used for "open module M = E â¦". Declarations involving the keywords as or public are changed in a corresponding way ("as" always goes with import, and "public" always with open). This change means that import directives do not affect the qualified names when open import/module is used. To get the old behaviour you can use the expanded version above. * Names opened publicly in parameterised modules no longer inherit the module parameters. Example: module A where postulate X : Set module B (Y : Set) where open A public In Agda 2.2.2 B.X has type (Y : Set) â Set, whereas in Agda 2.2.4 B.X has type Set. * Previously it was not possible to export a given constructor name through two different "open public" statements in the same module. This is now possible. * Unicode subscript digits are now allowed for the hierarchy of universes (Setâ, Setâ, â¦): Setâ is equivalent to Set1.
