fix(tests/lean): adjust tests to modifications to standard library 2014-12-01 05:16:01 +00:00			`prelude`
feat(frontends/lean/elaborator): add 'delayed coercions', add example demonstrating why the new feature is useful Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-06-27 01:39:23 +00:00			`inductive nat : Type :=`
feat(frontends/lean/inductive_cmd): allow '\|' in inductive datatype declarations 2015-02-26 01:00:10 +00:00			`\| zero : nat`

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 2015-01-25 04:23:21 +00:00			`attribute int.of_nat [coercion]`
