using haxl for data sources where dependencies are not statically known

[mwotton]

I have a learning algorithm that chooses variables to make decisions on that i'm trying to integrate into my Haxl-based project. The snag here is that the learning alg chooses those variable dynamically, making it hard to write a datasource that doesn't just fetch everything it might look at.

I think I can see a way around this using template haskell and introspecting on the generated decision tree, but if I'm overcomplicating it I'd love to hear about it.

I'm not sure I understand enough about your use case to comment. Could you give some example types to give more context?

Going to close this out because I'm not sure how we can make progress, feel free to re-open if you have more info.

It was an ill-formed question :) as I learned more I worked out how to do it.
