### From agenda

### Timebox overrun

## Schedule constraints

- ✅ Leo Balter is attending from California, preference for the ShadowRealm topic being discussed at the the last hour of the meeting, any of the days.
- ✅ The "module declarations" topic should come right after "module expressions" (Nicolò Ribaudo)
- Shu-yu Guo might not be able to attend Thursday, December 1; lowest priority items for @syg are Intl-related, so preference for Intl items on that day.
- ✅ Philip Chimento is available either the first or last hour of the meeting on any day, to present Temporal. Would prefer to be able to attend "Is ECMA-402 allowed to extend ECMA-262 prototypes?" as well, but that's not as high of a priority.
- ✅ Frank Yung-Fong Tang is attending from California, cannot attend afternoon on Thursday, December 1 and prefer to present all his topics in one batch, either in the morning of Wednesday, November 30 or the morning of Thursday, December 1.
- ❓ Santiago Díaz cannot attend Thursday, December 1 and needs to be present for "Prototype pollution mitigation / Symbol.proto"
- ✅ Jordan Harband would prefer to only attend for the first two hours of each day, and would like to be present for whatever is possible out of Array.prototype.group, Well-Formed Unicode Strings, set methods, iterator helpers, dedent, await ops, module declarations, Symbol.proto.
- ✅ Guy Bedford is attending from British Columbia for modules-related agenda items with a preference for the last 2-3 hours of each day.
