refactor(frontends/lean): constant/axiom are top-level commands, parameter/variable/hypothesis/conjecture are section/context-level commands Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-10-02 16:20:52 -07:00			`constant C {A : Type} : A → Prop`
refactor(frontends/lean): add 'attribute' command The new command provides a uniform way to set declaration attributes. It replaces the commands: class, instance, coercion, multiple_instances, reducible, irreducible 2015-01-24 20:23:21 -08:00			`attribute C [class]`
