[contingencies]

Yeah now try iterating. What used to get me is for some types $ is used only when de-referencing. It was terrible trying to track those errors down. Basically I loved perl but the language has a terrible design, inexcusable really. There was essentially no point in having types, it took all the worst parts of C and then reinvented them slightly differently with new syntax, twice per datatype. Glad to be rid of it.
