If we want that the second expression to be named "COLUMN_2". should we use a
hash table in struct Parse. We will push the names of all columns in the request
to it and generate names without collisions. I don't now anymore ways.
I would leave it as it is now.

Here I name all items (generate names) in expression list if it is needed.
I think this operation can be attributed to "expanding". Expanding is before
name resolving. At the resolving all items must be named.

You can use normal column names in ORDER BY, GROUP BY etc, I checked it 
in Postgre
(Postgre names expression the same way). I think it is OK.

commit 718d7e809291b1c48c1b5bc1a0c297906319394d
Author: Roman Khabibov <roman.habibov@tarantool.org>
Date:   Thu Mar 5 12:48:58 2020 +0300

     sql: unify pattern for column names

     Name resulting columns generated by an expression or <VALUES>
     construction by the "COLUMN_N" pattern.

     Closes #3962

     @TarantoolBot document
     Title: Column naming in SQL

     Now, every auto generated column is named by the "COLUMN_N"
     pattern, where N is the number of column in a query (starting)
     from 1). Auto generated column is a column in a query result
     generated by an expression or a column from <VALUES>
     construction.

     Examples:
     ```
     box.execute("VALUES(1, 2, 3);")
     ---
     - metadata:
       - name: COLUMN_1
         type: integer
       - name: COLUMN_2
         type: integer
       - name: COLUMN_3
         type: integer
       rows:
       - [1, 2, 3]
     ...
     box.execute("SELECT * FROM (VALUES (1+1, 1+1));")
     ---
     - metadata:
       - name: COLUMN_1
         type: integer
       - name: COLUMN_2
         type: integer
       rows:

     ...
     box.execute("SELECT 1+1, 1+1;")
     ---
     - metadata:
       - name: COLUMN_1
         type: integer
       - name: COLUMN_2
         type: integer
       rows:
       - [2, 2]
