trying to examine a var in LLDB in XCODE. can you execute functions at all, or just variable data?

http://ift.tt/1CdLW9L is the site i noticed, but i was having issues with Json::Value being human readable, so i watch to call "toString" on it.

It doesn't seem to enjoy that though when trying to do: p someVar.toString()

Does anyone know how i might get through this?
