Hi all, Tab and Anne suggested I ask about a use of objects here.

In https://api.csswg.org/bikeshed/?url=https://raw.githubusercontent.com/jyasskin/web-bluetooth-1/masked-data-prefixes/index.bs#device-discovery
defines some arguments to a function in which I want users to express
a map from integers or strings to a dictionary. One of the arguments
will look like {0x004C: {dataPrefix: [0x02, 0x15]}}, while the other
could be {0xFEAA: {dataPrefix: [0x10]}, "battery_service": {}}.

This is processed at
using explicit calls to `.[[OwnPropertyKeys]]()` and some other
ECMAScript operations.

Does this make sense, or should I have my users express these
arguments in some other way?

If this makes sense, would you like me to propose some WebIDL
operations that would make it easier?
