isLocalVariable added. Assignment / initialization analysis. Control whether a variable is changed in a loop at the beginning and at the end of the loop. Control whether a variable is captured in a closure. #KT-3175 Fixed. #KT-2266 Fixed. Tests for variable null safety and for variables is/as operations. Loop / closure / variable property tests are included. Old tests changed in accordance with KT-3175. In particular, all three of testSmartcastImpossible were fixed.
