Often we have `ResultT e IO a` as the return type of our primitive functions and we need to lift them into a monad stack that is also based on IO. This function accomplishes this by lifting a ResultT in a base monad of a monad stack into the stack. Signed-off-by: Petr Pudlak <pudlak@google.com> Reviewed-by: Klaus Aehlig <aehlig@google.com>
