This function is inspired by BQN's [⍉] though it is much less elegant
since Nix lacks multi-dimensional arrays. I thought this would be useful
to to avoid multiple `map`s over a single list if we want to return
multiple, separate values from it:
transpose (builtins.map (x: [ (calcA x) (calcB x) ]) myList)
# => [ [ (calcA a) … ] [ (calcB a) … ] ]
While this is quite elegant, it turns out that it is faster to write out
multiple maps:
[ (builtins.map calcA myList) (builtins.map calcB myList) ]
