Still think if there's no invoices it logically should be tested first.
If you don't want to repeat mentioning the array, how 'bout:

    @invoice or fail 'No invoices to process'
    ==> for @() {
        .process
    }

or equivalently

    @invoice or fail 'No invoices to process'
    ==> map {
        .process
    }

all assuming you don't like my original

    for @invoice || fail 'No invoices to process'
    {
        .process
    }
