[10:46:52] <wm-bb>	 <Toby> In the function this conversation jumped off from (Z11678), they are required to next cleanly. Here is the test: Z11683 (re @vrandecic: Can I mix brackets of different types? Or do they have to nest cleanly? Or can they overlap?)
[10:50:02] <wm-bb>	 <Toby> Please can someone help write a composition for Z12755 . I tried, using If (Z802), Is empty (Z813) (once as a condition on returning false, and then once to wrap around List without first element (Z812) for the final answer), but I got an obscure key-ID error, and I'm not sure if I got something wrong or if there is a bug.
[10:58:39] <wm-bb>	 <Toby> Please can a function maintainer connect my tests for Z810 and disconnect the failed inbuilt one.
[11:01:59] <wm-bb>	 <Toby> And similar at Z812
[11:05:38] <wm-bb>	 <Toby> I've also made tests for Z889 Z873 Z872
