The issue was that both "AS" and "OVER" are of type "NONE", so we were entering in the alias handling too early. The "OVER" was considered as the alias part, so when the "AS" comes out, the parser wrongly interpreted it as a second alias, and failed.

With this quickfix, I force the parser to disallow "OVER" as an alias-setting keyword, so that the whole windowing process in included in the expression, and "AS" is correctly recognized as the first (and only) alias-setting keyword.

Commits are showing the difference of the tokens management, by comparing before and after.

@williamdes This time, I picked up the right branch when I created the PR, and the tests are passing 😉
