Proof step 5 from proof validstatfields-put-array-norefval (previous step)

sk ∈ statfields(class), okval(val, st[r1 -- _type] .type .type), validstatfields(str, st), tdname∃(str, class), initdone(class, st) ⊦ is_referencevalue(val), validstatfield(str, sk, st[r1 -- i ', val])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ¬ is_referencevalue(val) ∧ validstatfield(str, sk, st) ∧ okval(val, st[r1 -- _type] .type .type) → validstatfield(str, sk, st[r1 -- i ', val])
Proof step 4:
¬ (¬ is_referencevalue(val) ∧ validstatfield(str, sk, st) ∧ okval(val, st[r1 -- _type] .type .type)), sk ∈ statfields(class), okval(val, st[r1 -- _type] .type .type), validstatfields(str, st), tdname∃(str, class), initdone(class, st) ⊦ is_referencevalue(val), validstatfield(str, sk, st[r1 -- i ', val])
