Proof step 14 from proof junkref-addobj (previous step)

junkrefs(str, refs, (addobj(r0, class, fis, st)[refs .first -- _type]) .type, addobj(r0, class, fis, st)), newref(r0, st) ⊦ r0 = jvmref, refs = [], junkref(str, refs .first, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 13:
refs = r + refs0, junkrefs(str, refs, (addobj(r0, class, fis, st)[r -- _type]) .type, addobj(r0, class, fis, st)), newref(r0, st) ⊦ r0 = jvmref, refs = [], junkref(str, r, st)

Rule argument

[speclemmaarg: refs ≠ [] ,r = refs .first ∧ refs0 = refs .rest ↔ refs = r + refs0 ,[refs, r, refs0] → [refs, r, refs0] ,T ,list-data ,references ,elim-list-c ]
