How do I reference a list by string?

So I’m trying to make a randomizer for the game PC Building Simulator. The problem is that not all parts are compatible with each other. I have this so far:

internals // this is ran silently above the title to init all variables because Perchance is kinda weird in its interpretation of the "code"
  [make_magic()] // [selected_case = mini_itx_case ? ]

output
  [case_compatibilities[case_size]]

case_sizes
  cube
  full_tower
  micro
  mid_tower
  open_frame
  super_tower

case_compats
  cube
    mini_itx_case
    micro_atx_case
    s_atx_case
  full_tower
    mini_itx_case
    micro_atx_case

make_magic() =>
  mobo_size = mobo_sizes.selectOne
  case_size = case_sizes.selectOne
  sel_case = case_compats[case_size]
  return sel_case

I omitted a lot of stuff. My make_magic() function is fine. sel_case returns the name of one of the top-level lists (e.g. mini_itx_case or s_atx_case) which is great, but it is a string, not a reference to the list. How do I convert the string sel_case to an actual list reference?

If sel_case is a string (i.e. the name of the top-level list that you want), then root[sel_case] will give you the actual reference to the list. The special root variable refers to the “top-level” / “root” node in your Perchance “tree” of lists/sub-lists.
