Proof step 3 from proof is_obj-putbar (previous step)

class+∃(str, st[r -- _type] .type .class), is_obj(r, putByteArray(bytes, r1, i, st)) ⊦ is_abstract(st[r -- _type] .type .class), is_obj(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ is_obj(r, putByteArray(bytes, r1, i, st)) → is_obj(r, st)

Rule argument

[crewrite-arg: isobj-putbar , F , [r, bytes, r1, i, st] → [r, bytes, r1, i, st] ]
