    (try body catch)
    
    Try something and catch errors. Body is any expression, and catch
    should be a form with the first element a tuple. This tuple should
    contain a binding for errors and an optional binding for the fiber
    wrapping the body. Returns the result of body if no error, or the
    result of catch if an error.
