Reference query metadata elsewhere in the file

[marknuzz]

Suppose I have a query that returns a set of tasks. I'd like to be able to reference things like :

• Number of total tasks returned by the query
• Number of completed tasks returned by the query
• Name of first task in the query

I'm thinking this could come in the form of an optional statement at the end of the query, like bind x and then I could reference it like this (is there something less verbose than html that would work here?):

### Today (<taskinfo query=foo var=completedcount/>/<taskinfo query=foo var=totalcount/>)`
```tasks
due before {{date+1d:YYYY-MM-DD}}
not done
sort by urgency
short mode
bind foo
```                                                                  .

Then in view mode, we'd see the header "Today 5/10", with the results of the query below the header, assuming the query returns 10 tasks, 5 of which are completed.

Hey @marknuzz, thank you for the idea!

The way you have written it, it would be touch to implement. I currently don't work with any rendered HTML except for tasks (checklist items) outside of query results (in the file directly when rendered).
What would be possible (easier) is to add this metadata at the top or bottom of the rendered query results. Like how it renders the total number of tasks at the bottom. The user could probably provide a template string (possibly similar to known templating languages from the eco-system like the templater-plugin) as part of the query and that template string would be rendered as part of the query results.
