Even worse, if one relies on PROCEDURE EXPOSE to isolate
variable scopes, one must put SYSCALLS('ON') in many subroutines
or EXPOSE necessary symbols at each level in the hierarchy.
(Wasn't it you who, several years ago, argued for balancing
each SYSCALLS('ON') with a matching SYSCALLS('OFF')? Doesn't
quite work. You'd need SYSCALLS(PUSH) and SYSCALLS(POP).
Or have SYSCALLS respect procedure scopes as ADDRESS, NUMERIC,
et. al do.)
