fix(jsii): Correctly handle singleton enums#535
Merged
Conversation
When an enum has only one option, TypeScript handles it in a special way and tries very hard to hide the enum declaration in favor of the sole member. This caused incorrect type names and kinds to be emitted in the JSII assembly, resulting in incorrect behavior. This uses a non-public part of the TSC API (possibly an omission from the hand-written type model), so it includes an additional guard check to fail explicitly in case the API's behavior happens to change in a breaking way. Fixes #231
