Problems arise when thinking about more complicated mathematical objects. I
don't know if I simply lack the appropriate Mathematica knowledge, but
years ago, when I implemented matroids in Mathematica, a matroid was simply
a list with 6 elements (groundset, representation matrix, and I forget what
else) and head Matroid. To access the elements of that list, you did stuff
like this:
lM = Map[If[# == 0, 0, 1] &, M[[2]][[#[[2]] & /@ M[[3]], #[[2]] & /@
M[[4]]]], {2}];
I don't miss that aspect of Mathematica one bit! Python objects are so much
nicer, and we still get lambda functions when we need them.
Also, it might be experience, but I spent WAY more time debugging my
Mathematica code than debugging my Python code.
