makeProvisionalBinding	back to summary
private NBinding makeProvisionalBinding(NType targetType) If we can't find the attribute in the target type, create a temp binding for the attribute. If later on the target type defines the attribute, that definition replaces the temp binding, and any references to the temp binding are updated to refer to the new definition. We never create temp bindings for attributes of native types, as the attributes of native types are expected to be fully resolved. This strategy is a temporary solution for inferring the types of attributes on targets that are not yet resolved. This whole approach needs to be replaced by dataflow analysis.
