Proof step 59 from proof compat-put (previous step)

compatmode(str, st), compatrefs(str, st), compat(str, val, ty, st), initdone(class0, st), compatfields(str, jvmref, statfields(class0), st), class∃(str, class0) ∨ interface∃(str, class0) ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, r -- mkfs(class, ty, fieldvar) ' = _uninit, compatfields(str, jvmref, statfields(class0), st[r -- mkfs(class, ty, fieldvar) ', val])

And obtained the following new goals

Proof step 36:
⊦ compatfields(str, r, sks, st) ↔ (∀ sk. sk ∈ sks → r -- sk ∈ st ∧ is_fskey(sk) ∧ compat(str, st[r -- sk], sk .fs .type, st))
Proof step 58:
compatmode(str, st), compatrefs(str, st), compat(str, val, ty, st), initdone(class0, st), compatfields(str, jvmref, statfields(class0), st), class∃(str, class0) ∨ interface∃(str, class0) ⊦ mkfs(class, ty, fieldvar) ' = _length, ty = void_type, r -- mkfs(class, ty, fieldvar) ' = _uninit, ∀ sk. sk ∈ statfields(class0) → jvmref -- sk ∈ st[r -- mkfs(class, ty, fieldvar) ', val] ∧ is_fskey(sk) ∧ compat(str, st[r -- mkfs(class, ty, fieldvar) ', val][jvmref -- sk], sk .fs .type, st[r -- mkfs(class, ty, fieldvar) ', val])
