Proof step 4 from proof putBar-lastrec (previous step)

⊦ putByteArray([] + by ', r, i, st) = (putByteArray([], r, i, st)[r -- (i + n→i(# [])) ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ putByteArray(by ', r, i, st) = st[r -- i ', byteval(by)]
Proof step 3:
⊦ putByteArray([], r, i, st) = st

Rule argument
