Typings of `current()` don't reflect that returned object is not a draft

[robatwilliams]

🐛 Bug Report

The typings of current() state that the input and return types are the same. This doesn't reflect that the function unwraps drafts.

Link to repro

const draft = immer.createDraft({ a: true });
immer.current(draft);

To Reproduce

Observe typings of the returned object. Runtime object is not a draft, but typings indicate that it is.

Observed behavior

Return type is the same as the input type.

export declare function current<T>(value: T): T;

Expected behavior

Return type is the type of thing whose draft was input.

export declare function current<T>(value: Draft<T>): T;

Environment

We only accept bug reports against the latest Immer version.

• [x] I filed this report against the latest version of Immer
