Call for Testing

An important step for RFC implementation is for people to experiment with the implementation and give feedback, especially before stabilization. The following RFCs would benefit from user testing before moving forward:

  • No RFCs issued a call for testing this week.

If you are a feature implementer and would like your RFC to appear on the above list, add the new call-for-testing label to your RFC along with a comment providing testing instructions and/or guidance on which aspect(s) of the feature need testing.

Quote of the Week

Now macros are fine, I mean we use them for implementing internals and you know if you have something that [...] needs to be implemented for lots and lots of different concrete types, then macros are a fine choice for that, but exposing that to users is something to be very careful about.
