Proof step 6 from proof getbooleanarray-length (previous step)

okarray(r, boolean_type, st), r ∈ st ⊦ st[r -- _length] .intval = n→i(# booleanvalues(getarray(r, 0, st[r -- _length] .intval, st))), r = jvmref

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ # booleanvalues(vals) = # vals
Proof step 5:
okarray(r, boolean_type, st), r ∈ st ⊦ st[r -- _length] .intval = n→i(# getarray(r, 0, st[r -- _length] .intval, st)), r = jvmref
