Proof step 3 from proof putBar-unrec (previous step)

val = byteval(by), is_bytevalue(val) ⊦ (putByteArray(bytes, r, i0 + 1, st)[r -- i0 ', val]) = putByteArray(by ' + bytes, r, i0, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ (putByteArray(bytes, r, i0 + 1, st)[r -- i0 ', byteval(by)]) = putByteArray(by ' + bytes, r, i0, st)

Rule argument
