Not sure there is a way to achieve that. As `get` copies the value of an option from the value value of the global, what should be the value for a global that doesn't exist?
In this specific case I think you might want to provide a default by setting "email_to=" so that `get trace_errors.error_email = email_to" can work but error email is disabled as it's empty.
