I feel the exact same way. They can be insanely powerful, but the syntax is insanely off-putting.

And the documentation is still pretty sparse.

> Eventually I want to write a good baseline library to use for my source generators -- simplifying finding definitions with attributes, mapping types to System.Type, adding some basic pattern matching for structures -- but haven't found a way to do it that's general enough while being very useful.

I'd use it in a heartbeat. The new ForAttributeWithMetadataName function has been a big help, but everything else feels like a totally different language to me.
