2. Technical agenda

2.1. Review of pull requests

2.2. What about fn:chain?

   We had a couple of meetings discussing the proposal to replace fn:chain
   with fn:compose. The PR for discussion this week simply removes
   fn:chain. (In previous straw polls, no one preferred "only fn:chain";
   this PR changes the status quo to reflect that.)

   I don't expect there's a lot of new technical ground to cover here, so
   we'll attempt to time box the discussion. Ultimately, I hope the CG can
   express a clear consensus and that everyone in the minority can accept
   that consensus.

   See PR [91]#1984: 882 Drop fn:chain, and PR [92]#1894: Additional
   examples to fn:chain
