Proof step 27 from proof unchanged-fits (previous step)

st[r -- sk] = st0[r -- sk], st0[r -- _type] = st[r -- _type], unchanged(str, st0[r -- sk] .refval, st, st0), unchanged(str, r, st, st0), is_referencevalue(st0[r -- sk]), fits(st0[r -- sk] .refval, sks0, st), fits(st0[r -- sk] .refval, sks0, st0), is_arraytype(st[r -- _type] .type), is_indexkey(sk), sk .index < st[r -- _length] .intval, st0[r -- _length] .intval ≤ sk .index, 0 ≤ sk .index, 0 < st[r -- _length] .intval, st0[r -- _length] .intval < st[r -- _length] .intval ⊦ r = jvmref, junkref(str, st0[r -- sk] .refval, st), junkref(str, r, st)

User applied rule cut formula

And obtained the following new goals

Rule argument

[fma-arg: st0[r -- _length] = st[r -- _length]]
