Proof step 6 from proof javavalues-in (conclusion)

⊦ val ∈ mkjavavalues(refs) ↔ is_referencevalue(val) ∧ val .refval ∈ refs

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ mkjavavalues([]) = []
Proof step 5:
∀ val. val ∈ mkjavavalues(refs0) ↔ is_referencevalue(val) ∧ val .refval ∈ refs0 ⊦ val ∈ mkjavavalues(r + refs0) ↔ is_referencevalue(val) ∧ val .refval ∈ r + refs0

Rule argument

[VARWITHVARSEQSARG : refs, ()]
