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
    }

Ah, I missed that last one when you originally posted it.

All three of those are quite sufficient solutions in my mind.

p.s. Could the latter 'for @foo || fail { }' cause confusion with 'for 
@foo {} or fail' ?
