We add a virtual node (`CompileTimeBindingPatternStart`) as the first child of `CompileTimeBindingPattern` which holds the identifier underneath it, so that it is checked just before the type expression of the `CompileTimeBindingPattern`. When we reach this virtual node during check, we add `.Self` as a name in the current scope, and when we reach `CompileTimeBindingPattern` we remove it from scope, which ensures it's present during only the checking of the type expression for the compile time pattern. At the moment the `.Self` has a different type (it's a `TypeType`) than other `.Self` in the facet type (which are a single `FacetType`), but the intention is to immediately substitute it out of the facet type entirely, replacing it with a reference to the compile time binding (a `BindSymbolicName`) itself. A TODO has been added for this. --------- Co-authored-by: Jon Ross-Perkins <jperkins@google.com>
