[See the crash below, starting with the "which,'blah" statement.
Thing is, it's impossible to SAVE,/SYSTEM_VARIABLES without getting
this one bundled in there. But since I'm now doing them one-by-one
using assignments to/from "normal" variables, it's easy to treat this
one as yet-another variable-that-must-not-be-named. The other variable-
that-must-not-be-named is !NULL, which is read-only, so one would not
expect it to be assignable - the funny thing is that it doesn't give
the same error message as assignments to e.g. !PI:
IDL> !pi=!pi
% Attempt to write to a readonly variable: !PI.
IDL> !null=!null
% Variable is undefined: <UNDEFINED>.
This kind'a makes sense, I suppose, but was still a big surprise to me
