Description
Currently, MissingField and MissngVar give the same error. Would be nice if missing field gave a different eror.
In contrast, here's what C# shows:
Foo x = new Foo();
var y = x.MissingField + MissingVar;
-
'Program.Foo' does not contain a definition for 'MissingField' and no accessible extension method 'MissingField' accepting a first argument of type 'Program.Foo' could be found (are you missing a using directive or an assembly reference?)
-
The name 'MissingVar' does not exist in the current contextt
