[racket] Help needed representing data | 2d hashes?

The Perl code keeps the encodings in a separate list, but I prefer
this representation you showed. (i.e, you're interpretation was
intended)

Thank you both very much for helping me. I've got all my data
represented now using YC's suggestion. :-)
