Smaller things:+
−
+
−
- maybe <type>_perm whould be called permute_<type>.simps;+
−
  that would conform with the terminology in Nominal2+
−
+
−
- we also need to lift the size function for nominal+
−
  datatypes+
−
+
−
Bigger things:+
−
+
−
- nested recursion, like types "trm list" in a constructor+
−
+
−
- define permute_bn automatically and prove properties of it+
−
+
−
- prove renaming-of-binders lemmas+
−
+
−
- strong induction rules+
−
+
−
- check support equations for more bindings per constructor+
−
+
−
- For binding functions that call other binding functions+
−
  the following are proved with cheat_tac:+
−
    bn_eqvt, bn_rsp, alpha_bn_rsp, constr_rsp+
−
+
−
- store information about defined nominal datatypes, so that+
−
  it can be used to define new types that depend on these+
−
+
−
- make parser aware of recursive and of different versions of abs+
−
+
−
Less important:+
−
+
−
- fv_rsp uses 'blast' to show goals of the type:+
−
  a u b = c u d   ==>  a u x u b = c u x u d+
