is_failure

Checks if an object is of <code>failure</code> class

Allows wrapping values in success() and failure() types to capture
the result of operations, along with any status codes. Risky expressions can be
wrapped in as_result() and functions wrapped in result() to catch errors
and assign the relevant result types. Monadic functions can be bound together
as pipelines or transaction scripts using then_try(), to gracefully handle
errors at any step.
