(html didn't post well before, re-posting both quantlib-dev and quantlib-users)
I've been writing quant software for almost 20 years, and this is my first look at quantlib. It's very impressive, but I have two design questions that I wanted to float in the quantlib-dev list, and see what kind of thoughtful responses there might be. No need to respond instantly: I'd like to hear considered responses.
This is all descended from the Observer design pattern, plus some other support. Which is nice, I did a bunch of event-driven systems back in the 1990s, very cool. And it scales reasonably well, within a single OS and machine.
1) Poll: How many users/developers have ever wanted to use this product without the Observer design pattern, which I find impedes distributed computing, general transparency, and audit?
2) Has anybody thought about how one might implement the subject matter independently, as Singleton, and embed it within a design pattern of ones own choosing? E.g. I'd like to be able to use these methods in a Command/Visitor context, but see a rewrite as codebase divergence, a big no-no for me.
Thanks,
Dave Eaves
