Proof step 35 from proof isarray-putbar (previous step)

by ' + bytes0 ≠ [], okbytearray(r1, st), is_array(r, putByteArray((by ' + bytes0) .rest, r1, i + 1, st)[r1 -- i ', byteval((by ' + bytes0) .first)]), ∀ r, r1, i, st. is_array(r, putByteArray(bytes0, r1, i, st)) ∧ okbytearray(r1, st) → r = r1 ∨ is_array(r, st) ⊦ r = r1, is_array(r, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 33:
⊦ r ≠ r0 → (is_array(r0, st[r -- sk, val]) ↔ is_array(r0, st))
Proof step 34:
okbytearray(r1, st), is_array(r, putByteArray(bytes0, r1, i + 1, st)), ∀ r, r1, i, st. is_array(r, putByteArray(bytes0, r1, i, st)) ∧ okbytearray(r1, st) → r = r1 ∨ is_array(r, st) ⊦ r = r1, is_array(r, st)
