Clickhouse tuples not supported #2338
Description
Clickhouse tuples are not supported. The following errors ParserError("Expected: end of statement, found: .1 at Line: 1, Column: 22").
SELECT t.1 FROM x
This is a valid Clickhouse way of accessing tuple elements. See https://clickhouse.com/docs/sql-reference/functions/tuple-functions#tupleelement. It is some syntactic sugar to tupleElement(t, 1) which does work.
Request: Make the above query work, and similar ones.
SELECT t.1 FROM x
SELECT (1, 2, 3).2
SELECT arr[1].1 FROM t
SELECT arr[1].1.2 FROM t
