refactor(builtin): only load the kernel and natural numbers by default Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-12-30 21:35:37 +00:00			`Import int.`
Add natural numbers. Fix how coercions and overloads interact (switch to approach used in C++). Add notation for natural and integer arithmetic. Rename m and u universe variables to M and U. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-09-02 19:24:29 +00:00			`Check 10 + 20`

feat(frontends/lean): rename command Set to SetOption It is not nice to have Set as a reserved keyword. See example examples/lean/set.lean Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-12-19 05:18:45 +00:00			`SetOption lean::pp::coercion true`
