- Added to `mruby-binding-core` - `Binding#local_variable_defined?` - `Binding#local_variable_get` - `Binding#local_variable_set` - `Binding#local_variables` - `Binding#receiver` - `Binding#source_location` - `Binding#inspect` - Added to `mruby-proc-binding` - `Proc#binding` The reason for separating `Proc#binding` is that core-mrbgems has a method that returns a closure object to minimize possible problems with being able to manipulate internal variables. By separating it as different mrbgem, each user can judge this problem and incorporate it arbitrarily.
