It seems the main complaint is about confusing shapes / dimensions. Xarray has already be mentioned, but this is a broader concept, called named dimensions, sometimes also named tensors, named axes, labeled tensors, etc, which has often been proposed before, and many implementations exists.

Someone just need to write a new named multi-dimentional array processing library in Dlang with Mir since it's more intuitive and faster than venerable Fortran library that's being widely used by array languages including Matlab, Julia, etc [1], based the implementation on the methodology presented in the seminal book by Hart [2], problem solved.
