    SQL comments - commenting out code for earlier versions
    In MySQL, it's possible to comment out portions of code that you only want to work in specific MySQL versions:

    i.e.
    CREATE DATABASE /*!32312 IF NOT EXISTS*/ `a` /*!40100 DEFAULT CHARACTER SET latin1 */;

    The problem with this, is that the decimal point is omitted - and there's a real assumption that with something like 3.23.12 the "12" portion never exceeds 99.

    When I look at 5.0, MySQL is currently at 5.0.60 - and there are still minor changes happening. 5.1 is at 5.1.25, and not even GA. Assuming that 5.1 does the same community/enterprise split and shuffles through releases in even numbers, how long will it take before we have 5.1.100?

    If we do get there, the SQL commenting feature will need upgrading.
