Variable paging of named variables

[sim642]

The specification doesn't say how the start and count arguments to the variables query are supposed to interact with the filter argument:

• With indexed filter, it's more-or-less obvious.
• With named filter, not so much. Does filtering apply in this case at all?
• Without a filter, it's even more underspecified. If paging applies to named variables, then how are variables supposed to be counted in case there are both? Should it essentially behave like there's one long list of both kinds of variables (but which of them come first then)? Or can they be arbitrarily interleaved?

Coincidentally, a different part of the specification explicitly talks about paging named variables:

    /**
     * The number of named child variables.
     * The client can use this information to present the variables in a paged
     * UI and fetch them in chunks.
     * The value should be less than or equal to 2147483647 (2^31-1).
     */
    namedVariables?: number;

But that's under a completely unrelated request.
