array-interop: Request for feedback

[vitiral]

Please see anowell/are-we-learning-yet#14. I would like for the major rust array crates to be able to have interop without friction. I would love your feedback

Thanks for writing this up and sharing.

I'm very busy for the next couple of weeks but after I'll have some time to properly review and put some ideas forward. In the mean time I'll try to keep up with the discussion!
