Proof step 2 from proof eqmode-length (previous step)

r ∈ st0, st =mode st0, st0[r -- _length] .intval < st[r -- _length] .intval ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ st =mode st0 ↔ st = st0 ∨ (∃ r, class1. st = (st0[r -- _type, typeval(mkclasstype(class1))][_mode, throw(r, mkclasstype(class1))]) ∧ newref(r, st0))

Rule argument

[crewrite-arg: equalXmode, F, [st0, st] → [st0, st]]
