It reminds me the experience I had when working with Scala, I really tried to like it but the mind-boggling amount of features created similar issues.

It took me about 2 years to feel somewhat comfortable but I'd still run into code where someone decided to use their own set of unconventional favourite features, requiring me to learn yet-another-way to do the same thing I had seen done in other ways.

I just got tired of it, didn't feel more productive nor enlightened...

Don't understand this complaint about Rust, but I'll give you Scala. Never seen a language so finely tuned to empower architecture astronauts to make terrible decisions. And boy do they make terrible decisions.
