I recently started using RRDtool, and I wanted to take advantage of the module RRDTool::OO. However, I find no way to create a COMPUTE data source. A peek in the source seems to confirm that this was not implemented.

The author says

For the experienced user, however, it provides full access to rrdtool's API (if you find a feature that's not implemented, let me know).

So, before posting him a bug or something, I would like to check with you if I am right or wrong. Can you confirm that you can't create a COMPUTE data source in RRDTool::OO other than accessing the API directly?

Thanks
