Alex Lam S.L	8a4f86528f	fix side-effects detection on switch statements (#1678) ... extension of #1675	2017-03-26 12:05:44 +08:00
Alex Lam S.L	b19aa58cff	fix has_side_effects() (#1675) ... `AST_Try` is an `AST_Block`, so besides try block we also need to inspect catch and finally blocks for possible side effects. Also extend this functionality to handle `AST_If` and `AST_LabeledStatement` while we are at it. fixes #1673	2017-03-25 23:03:26 +08:00
