Cumbersome globals, bug-inducing as well (Ricatti solver issue)
Terrible pipe operator
weird choice of having map take function first then data, even though map is a data function itself. This causes issues with the pipe operator idea as well.
Column-major vs row-major
Need good internet for adding packages (can’t use it effectively when outside of town)
Poor but understandable reshaping of vectors of vectors into matrices (especially for multidimensional arrays)
Unnamed vectors, no annotations possible
returning multiple values from map in consistent way.
No pattern matching (data diffusion, exit condition for value comp only using if)
