Like I said, I suspect that the MySQL mailing lists are configured to do that. Probably to cut down on the worse effects of spam or something like that. I speculate because I don't have admin access to this list even though I run the project. The list still belongs to MySQL, Inc.

Got it, though you really should have used a bug tracker entry instead:

https://gna.org/bugs/?group=mysqlpp

That gives it a visible placeholder in case I don't get to it immediately.

As for the code, the basic idea is okay, but it's too complex for an example. Also, I believe that if a properly descriptive name for a thing contains "and", it's a sign of a bad design: you haven't factored it correctly if it's doing two separate things. I reworked your code to just collect statistics, which fixes both problems.

Although you have to squint to see the resemblance between this new example and your conception of it, please understand that it was still valuable. Criticizing and fiddling with someone's code is easier than starting from scratch, so your contribution did help.
