Proof step 23 from proof validstatfield-put-array-norefval (previous step)

okval(val, st[r1 -- _type] .type .type), validstatfield(str, sk, st), is_fskey(sk) ⊦ is_referencevalue(val), (initdone(sk .fs .class, st) → validfield(str, jvmref, sk, st[r1 -- i ', val])) ∧ tdname∃(str, sk .fs .class) ∧ sk ∈ statfields(sk .fs .class)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 22:
sk = fs ', okval(val, st[r1 -- _type] .type .type), validstatfield(str, sk, st), is_fskey(sk) ⊦ is_referencevalue(val), (initdone(fs .class, st) → validfield(str, jvmref, sk, st[r1 -- i ', val])) ∧ tdname∃(str, fs .class) ∧ sk ∈ statfields(fs .class)
