Thanks for bringing this up! Currently, we have no recommendation, but we would love to work on better IDE support with the Swift community. This is also a good question...

There is not, unfortunately. I’m definitely seeing possible intensional uses in things like lazy tensor tests, but it appears to me that these warnings are only affecting the end user...

> @rxwei when I said `x.reshape()` I meant is there any way to have error messages with `.reshape()`. There is no way of doing so, unfortunately.

> @rxwei one last thing, what file would be appropriate to place these warnings in? This should be implemented modularly as part of [the raw operator generation script](https://github.com/tensorflow/swift-apis/blob/master/Sources/TensorFlow/Bindings/generate_wrappers.py).

Thanks for the write-up! I'll tag #322, [`Numeric.Magnitude`](https://forums.swift.org/t/removing-the-comparable-constraint-for-numeric-magnitude/26498) and [`AdditiveArithmetic`](https://forums.swift.org/t/additivearithmetic-conformance-synthesis-for-structs/26159) discussions on the evolution forum so that people looking at this issue can also get some context from those threads....

Happy to start with a discussion on the mailing list going forward!

I do not think passing Swift closures needs anything heavyweight like virtualization or type system changes. All we need is to get its function pointer and maintain the lifetime of...
