Add Real arithmetic. Fix elaborator for coercions. Now, two overloads are considered ambiguous if they need the same number of coercions. Improve pretty printer for nest infix operators with same precedence and associativity. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2013-09-02 20:20:00 +00:00			`Show 1/2`

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`
