Re: bogus 'unsafe variable' warning with try-else

I guess the best option (and the one intended by OP) is to file:close/1 as
soon as possible.

Thus Anthony's proposition would be unsuitable (though valid) and OP would
need something like Kostis' case proposition.

I don't get why the scoping rules differ between try…after and case…of. I
don't think they should (but I am surely missing an edge case where the
difference makes sense).
