Thanks for the clarification Chris.

I had forgotten to mention this in my review.  The synchronous functions
offer three nice error handling options out of the box: throw_error,
ignore_error and assign_error.  And the user can easily provide a custom
solution of their own.  The names are spelled clearly and there can be no
doubt about what they do.  I like this interface.
