Support pooled connections without the need for a second library

[solonovamax]

It would be very nice if pooled connections could be supported without the need for an additional library.

Do you have a concrete example that would benefit in a way that outweighs the cost of added complexity and the deviation from the KISS principle ("keep it simple, [...]") and the UNIX philosophy ("Write programs that do one thing and do it well. Write programs to work together. [...]")?

In addition, the separate library can also be used for databases, files, network streams, and other resources. Assuming you only mean a connection pool without cluster support.
