@call decorator for callable objects?

This is what I did in rescript-bun - a regular describe function, and a Describe module with skipIf: https://github.com/zth/rescript-bun/blob/main/src/Test.res#L53-L105

describe("whatever", () => { ... })

vs

Describe.skipIf(true, () => { ... })

Makes it pretty easy to work with, just capitalize describe and add skipIf. Not as discoverable as describe.skipIf would be though of course.
