Why is this validation process driven by a %magic command?
Magics were made for functionality that cannot be implemented directly
within a Stellar execution environment. Often for answering questions 'about'
the execution environment itself. For example `%vars` or `%functions` or
`%globals` all tell us about the Stellar execution environment.
This logic doesn't seem like a good fit for a %magic, unless there is a
limitation that I am not understanding. This could be implemented, I would
argue more simply, as a regular Stellar function.
