Not just too much stuff IMO. I kind of like all the features.
The main problem in my eyes is not enough volunteers (although they are doing a superhuman effort) to get it into the production level it needs to get more widespread adoption. The other problem is that Python already has a huge amount of libraries and is considered to be "good enough" feature wise, so it's hard to attract interest.
I do enjoy reading Raku code and think it is super neat as this do it all post-modern language. Inertia is hard to overcome though.
Early on, there was some attempt at syntactic macros. I tried it. But it didn't work out. I hear there are efforts for another iteration. That would be just fantastic when it lands.
