It uses an implementation detail about the representation of closures, namely

[https://docs.julialang.org/en/v1.5-dev/devdocs/functions/#Closures-1](https://docs.julialang.org/en/v1.5-dev/devdocs/functions/#Closures-1)

But I think this is an implementation detail, and not part of the official API, so I would not rely on this.
