Making "AS" in table writer more flexible due to dialect?

[xafero]

I have two questions:

• Could one make the methods in SqlTextWriter virtual? (WriteSql, WriteCommaSpaced, WriteDelimited, WriteList, WriteConstraint)
• Could one change the TableFactor to make "AS" writing optional or due to dialect? My DB does not allow for it in table alias.

protected void WriteAlias(SqlTextWriter writer)
    {
      if (Alias != null)
      {
           // NOT ALLOWED IN MY DB dialect: writer.WriteSql($" AS {Alias}");

	   // Somehow decide or delegate to dialect?
           writer.WriteSql($" {Alias}");
      }
    }
