Proof step 43 from proof junkrefs-put-badarrayindex (previous step)

junkrefs(str, refs, ty, st[r0 -- i ', val]) ⊦ junkrefs(str, refs, ty, st), is_array(str, r0, st)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ ¬ junkrefs(str, [], ty, st)
Proof step 42:
∀ str, ty, st, r0, i, val. junkrefs(str, acc, ty, st[r0 -- i ', val]) → junkrefs(str, acc, ty, st) ∨ is_array(str, r0, st), junkrefs(str, r + acc, ty, st[r0 -- i ', val]) ⊦ junkrefs(str, r + acc, ty, st), is_array(str, r0, st)

Rule argument

[VARWITHVARSEQSARG : refs, ()]
