test(tests/lean): remove data.nat dependency 2014-12-24 01:35:14 +00:00			`import 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
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 23:20:52 +00:00			`constant R : nat → nat → Prop`
