fix(tests/lean/uni_bug1): make sure test does not produce a 'used sorry' warning. Thus, the output behavior is the same when we compile lean with/without IGNORE_SORRY=ON 2014-09-26 16:42:31 +00:00			`import data.nat.basic data.prod`
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 nat prod`
fix(library/unifier): we should preprocess choice constraints before we start solving any constraint, fixes #85 Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-08-21 23:42:59 +00:00
