Misuse check: parameters that should've been used

[BenWoodworth]

At the end of an iteration, if a parameter wasn't used, but was in the previous iteration, then there must be impure control flow occuring. It should be quick to check this after an iteration, and throw an exception if it happens

[BenWoodworth]

Note that there are cases where it's okay that parameters aren't used. E.g.

parameterize {
    val a by parameterOf('a')

    val b by parameter {
        a // Uses `a`, but this lazy arguments block only runs on the first iteration (a1)

        listOf("${a}1", "${a}2")
    }
}

Because of this, it may be more complex to track, so may not be worth implementing
