[00:21:26] <wm-bb>	 <Toby> Al you seem to have figured out in Z15790 how to use Z805 and Z822. Is it possible to make valid test cases for those?  I know you won't be able to link them, but it will help others to see how they're meant to work.
[01:24:32] <wm-bb>	 <Toby> Can someone help me understand validators?  I tried this, and am confused: Z15791
[01:25:58] <wm-bb>	 <Toby> I expected Z140 to be mean the same thing as Z15717, so was already confused that the latter had been created.
[01:38:44] <wm-bb>	 <Toby> I've now checked the behaviour of some other inbuilt validators, and it seems that when they receive a valid thing, they return that same valid thing. If that's the intent I will flip the test case to "validate boolean(false) is false" which sounds strange to me. (re @Toby: Can someone help me understand validators?  I tried this, and am confused because it fails: Z15791)
[07:16:41] <wm-bb>	 <Al> Yes, I’ll add a couple. (re @Toby: Al you seem to have figured out in Z15790 how to use Z805 and Z822. Is it possible to make valid test cases for those?  I know y...)
[23:40:13] <wm-bb>	 <Al> Z805 isn’t easy to test https://www.wikifunctions.org/wiki/Talk:Z15796 (re @Toby: Al you seem to have figured out in Z15790 how to use Z805 and Z822. Is it possible to make valid test cases for those?  I know y...)
