@spec safe(function :: function(), arguments :: [term()]) :: {:ok, term()} | :error

Safe application of an anonymous function.

This is just like apply/2 but if the the anonymous function is unable to handle the call (raising either BadArityError or FunctionClauseError) then the :error atom is returned.

If the function evaluates successfully its reply is returned wrapped in an {:ok, result} tuple.
