Go does not support multi-dimensional slices, and that is a problem. I am not sure the numeric data types thing is such an issue. Python supports int, float, long and complex types. So does Go, with the slight annoyance you have to care a little more about the size of your number, and so you don't just label something 'long' and walk away safe in the knowledge it's kinda big. Numpy just makes Go's numeric data types available. The clever thing it does that Go does not is around arrays and operations on them - something we need to consider in Go land, carefully. The other stuff Numpy and Pandas makes available could be made available in Go, too and could abstract away the horrible stuff under the hood where you're resizing slices and creating multidimensional versions. I think the moment multi-dimensional slices are available, you can do everything you want, and with concurrency and therefore able to trivially exploit multi-core systems - that could be the killer feature. Maybe.
