* [x] `inline var foo`: Should not be allowed, it will break after the first assignment. Possibly for `lazy val` too. * [x] `inline class Foo`: Should not be allowed. * [x] `inline object Foo`: Should have a better error message. Currently _right-hand side of inline object Foo must be a constant expression or a function_. * [x] `inline type Foo`: Should not be allowed, it makes not sense.
