    Description

      mysql> CREATE VIEW v3 AS SELECT * FROM (SELECT s1 FROM t1) AS x;
      ERROR 1349 (HY000): View's SELECT contains a subquery in the FROM clause

      and http://bugs.mysql.com/bug.php?id=12755

      specifically Eric Bergen's comments about the complexity of removing this restriction. It should be doable without too much hassle, and as we can see from the comments, it would resolve a lot of issues for people.
