Proof step 8 from proof is_obj-put-samefield-01 (previous step)

class+∃(str, st[r -- _type] .type .class), is_obj(r, st), okval(val, fs .type) ⊦ fs ' = _type, is_obj(str, r, st[r -- fs ', val]), is_abstract(st[r -- _type] .type .class)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
fs = mkfs(class, ty, fieldvar), class+∃(str, st[r -- _type] .type .class), is_obj(r, st), okval(val, ty) ⊦ fs ' = _type, is_obj(str, r, st[r -- fs ', val]), is_abstract(st[r -- _type] .type .class)

Rule argument

[speclemmaarg: , class = fs .class ∧ ty = fs .type ∧ fieldvar = fs .field ↔ fs = mkfs(class, ty, fieldvar) ,[fs, class, ty, fieldvar] → [fs, class, ty, fieldvar] ,T ,fieldspec , ,elim ]
