feat(frontends/lean): rename 'using' command to 'open' Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-09-03 23:00:38 +00:00			`open tactic`
feat(library/tactic/apply_tactic): add option for 'refreshing' universe metavariables in the 'apply' tactic The new test ../../tests/lean/run/tactic27.lean demonstrates why we need this feature. The tactic 'apply @refl' is actually 'apply @refl.{?l}'. It is used inside of a repeat tactical. Each iteration of the 'repeat' may need to use a different value for ?l. Before this commit, there was not way to say we want a fresh ?l each iteration. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-07-08 23:55:11 +00:00
