Proper std::ref semantics #50

Closed ThePhD closed 9 years ago

ThePhD commented 10 years ago

This pull request ensures proper std::ref semantics and makes get and set on table obey those semantics.

A sol::ref type was added to make the lua.get<sol::ref<T>> less painful than lua.get<std::reference_wrapper<T>> syntax, and sol::ref<T> is just a using alias for std::reference_wrapper.

This looks like an API breaking change. If it is, then it might be postponed to v2.0.0 of sol rather than v1.2.0.

ThePhD commented 10 years ago

It's a breaking change of behavior, so this should probably be made a v2.0.0 change.

This pull-request's semantics have been sucked into #51 's change log, since it was necessary in the API fixing.
