Prioritised list of open issues

Which aggregates to include

Dealing with aggregates over mixed datatypes

Extensibility of aggregate functions
  - Seems consensus on URI, less on whether DISTINCT should be allowed

Issues where I think there is already consensus.

Subquery syntax (e.g. mandatory curly braces)
- I've not heard anyone speaking against braces recently.

What is the variable scope between main queries and subqueries?
- Only projected variables have scope outside a subquery.

Presence and syntactic detail of HAVING clause
- Seems consensus on the post-aggregate FILTER being called.

Can aggregate functions take DISTINCT as an argument a la SELECT  
- Seems consensus on yes.

What happens when expressions are projected with the same name as an  
existing variable?
- Seems consensus on it being an error.
