Would rewriting healthcare systems in enterprise Java or modern JS or Clojure actually improve them any compared to MUMPS? From my brief experience, the #1 MUMPS problem is that the syntax makes Perl and regex look legible. The two points that I miss in modern languages are: 1. There is absolutely nothing special you need to do when handling values out of the database compared to in-memory values 2. The nested data structure—it's like a nested Python dict, except each level can contain a value and children.
