> The inferred type of "delegate", "owner", "thisObject", "getDelegate()",
> "getOwner()" and "getThisObject()" within a closure has a few problems.
> 1) All should infer to {{Class<Type>}} when in a static context (and no
> nesting or delegation metadata is present).
> 2) {{getOwner()}} and {{getThisObject()}} infer to the enclosing type
> regardless of the object expression when inside a closure. And the same for
> {{getDelegate()}} if no delegation metadata is found.
> 3) {{getOwner()}} and {{getDelegate}} (if no delegation metadata is found)
> should infer to {{Closure}} within a nested closure block.
> {{StaticTypeCheckingVisitor#visitVariableExpression}} does this for "owner"
> and "delegate".
