Proof step 6 from proof isobj-putbar-02 (conclusion)

⊦ is_obj(str, r, putByteArray(bytes, r1, i, st)) ↔ is_obj(str, r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ is_obj(str, r, st) ↔ class+∃(str, st[r -- _type] .type .class) ∧ ¬ is_abstract(st[r -- _type] .type .class) ∧ is_obj(r, st)
Proof step 2:
⊦ is_obj(r, putByteArray(bytes, r1, i, st)) ↔ is_obj(r, st)
Proof step 5:
class+∃(str, st[r -- _type] .type .class), is_obj(r, st) ⊦ is_obj(str, r, putByteArray(bytes, r1, i, st)), is_abstract(st[r -- _type] .type .class)

Rule argument
