i've been keeping a vaguely interested eye on it for years, because it does look interesting. it has failed to make it to the front of my "learn this language next" priority queue due to the fact that i can't find anyone using it for
anything, not even a hobby project on github. also, the documentation is a bit sparse.
one killer feature that would make me start learning it immediately is good, well-documented qt bindings (i'm sure it is possible, since felix compiles down to c++, but with the sparse documentation i have no idea how i would go about getting it up and running, and insufficient motivation to first learn the language and then figure out how to do it).
