Quite true. I don't think we should bother supporting them (at least not right
away); just disable the feature for them.
The feature looks sound in principle and probably useful. Matt Armstrong had
some good comments on the surface
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=46988#20) to make it more
readable.
Maybe it would be useful to generalise it to other dynamic checks, such as 'no
consing', 'no lisp', 'no bytecode', 'no regexp', 'no signalling'?
