fix(library/unifier): bug in unifier priority queue Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-08-19 00:25:39 +00:00			`import logic`
fix(tests/lean): adjust tests since module 'logic' depends on nat We need that because of the definitional package 2014-11-23 01:34:05 +00:00			`namespace experiment`
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 nat : Type.{1}`
			`constant int : Type.{1}`
			`constant of_nat : nat → int`
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 of_nat [coercion]`
