Re: is anybody using 2.10.4?

Yes, I can separate it into another library, although I have to choose a
good name for it. Originally I wanted to put it to experimental subproject
in banana because it is experimental but then I noticed your comment there
that experimental is a virtual project.

>Also, there is some clash with what's available in diesel,

I do not see any clashes here, DIESEL is DSL to create RDF graphs in a
convenient way (at least after you will fix some annoying bugs). Current
annotation code is for "ORM-like usage". People in RelationalDB world often
connect tables to classes, it is natural to have similar practice with
semantic web: when you can move classes to RDF and vise-verses by
connecting annotations with class field. I thought that having such
features (of course not only annotations, but also some extra stuff) may
attract people from "Hibernate/Activate/Slick world".

>Have you considered the shapeless path instead?

What do you mean by shapeless path? I do not use shapeless directly in my
projects but I use libs like parboiled that make nice DSL on top of HLIST
And BTW shapeless uses some macroses inside. Macroses are not easy to deal
with (due to lack of good tutorials and docs and their too low-level
nature) but for some tasks like compile-time field extraction I find them
rather useful. They can also be used for more complex things like DSL-glue
together with implicits (new version Scala Rx uses them to extract reactive
variables) but I am not skilled enough with macroses to modify trees yet. I
think macroses and implicit/typeclasses stuff should complement each other.
