I think this can be done with a stored procedure. Magic tables with
side-effects seem weird.
Is there anything fundamentally difficult with supporting "PROCEDURE
foo()" as equivalent with "FUNCTION foo() RETURNS opaque" and "CALL foo()"
as equivalent with "SELECT foo()" and throw away the result. Then you
could define a function analogous to SHOW and a procedure analogous to SET
and can manipulate the values using the full expression language.
