Proof step 4 from proof bytearray-is-no-junk (previous step)

junkref(str, r, st), okbytearray(r, st) ⊦ is_array(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ okbytearray(r, st) ↔ okarray(r, byte_type, st)
Proof step 3:
junkref(str, r, st), okarray(r, byte_type, st) ⊦ is_array(str, r, st)

Rule argument

[speclemmaarg: ,okbytearray(r, st) ↔ okarray(r, byte_type, st) ,[st, r] → [st, r] ,F ,okfuns , ,okbytearray-01 ]
