I think that may be to do with not being allowed to address "a slice" of an
array, eg.
  #undef D["Arr"][0]
  #undef D["Arr"][1]
and
  #undef D["Dict"]["1"]

work "as advertised".

Thanks, yes, I had figured that out, but am not happy with it.

#undef D["Arr"][0]
#undef D["Arr"][1]
#ifdef(D["Arr"])
  #debug "D_Arr\n"
#end

This prints "D_arr", so D["Arr"] isn't gone, it's just empty. Don't know how
harmful it is, if at all?

Thanks,

This works around it:

#declare D["Arr"]=""
#undef D["Arr"]
