`jsii` used to fail when trying to generate deprecation warnings and given a statement like this: ```ts export function propertyInjectionDecorator<T extends Constructor>(ctr: T) { // Important for the bug: the anonymous class extends something, *and* // declares a method. return class extends ctr { public someMethod(): string { return 'abc'; } }; } ``` The reason is that during generation of deprecation warnings we iterate over all classes and methods (both exported and unexported), and generate a symbol identifier for every method; but this class is anonymous so it doesn't have a symbol, and generating the identifier fails with the error: ``` TypeError: Cannot read properties of undefined (reading 'flags') at symbolIdentifier (.../jsii/lib/common/symbol-id.js:40:17) ``` Handle this by handling the case where we don't have a symbol and returning `undefined`.
