TS Error: Unable to resolve signature of property decorator when called as an expression.

[speigg]

The typings for the tracked decorator in the npm package are missing an optional specifier:

export default function tracked(obj: object, key: string | symbol, desc: PropertyDescriptor): void;

should be:

export default function tracked(obj: object, key: string | symbol, desc?: PropertyDescriptor): void;

Thanks for bringing this up, can you open a PR to fix by chance? If not I should be able to get to it soon.

It's not actually clear to me why the type definitions you are generating are missing the optional specifier. The .ts source has the correct typings.

This line is probably the incorrect one: https://github.com/pzuraq/tracked-built-ins/blob/master/addon/-private/decorator.ts#L40

Oh, I guess the parameters in the actual implementation are not actually included (in the generated declarations). I'll open a PR
