Distinct Count

[Daniel Fagnan]

I'm wondering if I'm missing something to do a distinct count on some property.

With this query: `SELECT count(DISTINCT stream)`, where `stream` is a non-transient property. I get the following error:

```

skyd.ExecutionEngine: Unable to merge: [string "..."]:199: attempt to index local \'a\' (a nil value)

```

This also happens on every property, transient and non-transient. However, a simple `count()` works perfectly.

Any Thoughts?

Ahh, it seems I needed to have some sort of `GROUP BY` clause. That fixed the issue.

Daniel-

I'm glad you got it figured out. The parser definitely needs some work in how it reports errors. It's pretty rough right now. There's a large refactor of the query/ast package in the LLVM branch which should get merged over fairly soon.

Thanks. I've been keeping track somewhat of the progress on that branch. Things are looking pretty awesome in there.
