• SR-1846 "Variable used in its own initial value" error when using a function (not a variable) of the same name

Issue Description:

Consider following example:

struct S {
  func foo(x: Int) {}

  func bar() {
    let foo = foo(x: 42)
  }
}

It produces following error:

variable used within its own initial value

Which doesn't really make much sense, instead it should produce an error which suggests to add `self.` before method or variable use e.g. `let foo = self.foo(x: 42)`
