Proof step 3 from proof mode-03 (conclusion)

⊦ oktype(val, ty, st[_mode, val0]) ↔ oktype(val, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ jvmref -- mkfs(`java.lang.Object' .class, void_type, `mode' .field) ' = _mode
Proof step 2:
⊦ oktype(val, ty, st) ↔ okval(val, ty)

Rule argument

[speclemmaarg: , jvmref -- mkfs(`java.lang.Object' .class, void_type, `mode' .field) ' = _mode ,[] → [] ,T ,specialkeys , ,mode-01 ]
