Proof step 5 from proof in-init-04 (previous step)

∀ r, r0, j, st. r -- _type ∈ addarray(r0, vals0, j, st) ∧ r ∈ addarray(r0, vals0, j, st) → r -- _type ∈ st, r -- _type ∈ addarray(r0, val + vals0, j, st), r ∈ addarray(r0, val + vals0, j, st) ⊦ r -- _type ∈ st

And obtained the following new goals

Proof step 3:
⊦ addarray(r, val ' + vals, i, st) = (addarray(r, vals, i + 1, st)[r -- i ', val])
Proof step 4:
r -- _type ∈ addarray(r0, vals0, j + 1, st), r ∈ (addarray(r0, vals0, j + 1, st)[r0 -- j ', val]), r ∈ addarray(r0, vals0, j + 1, st), ∀ r, r0, j, st. r -- _type ∈ addarray(r0, vals0, j, st) ∧ r ∈ addarray(r0, vals0, j, st) → r -- _type ∈ st ⊦ r -- _type ∈ st
