Proof step 40 from proof validstatfields-put-statfield-06 (previous step)

sk = fs ', fs = mkfs(class0, void_type, `initstate' .field), is_fskey(sk) ⊦ class0 = class, validstatfields(str, statfields(class), st[jvmref -- sk, val]) ↔ validstatfields(str, statfields(class), st), sk ∈ statfields(class)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 39:
⊦ class0 = class, validstatfields(str, statfields(class), st[jvmref -- mkfs(class0, void_type, `initstate' .field) ', val]) ↔ validstatfields(str, statfields(class), st)

Rule argument
