I said it _doesn't_ give you enough power to justify the baggage, apologies if I wasn't clear. Iteration/modeling is one of my gripes in fact. The only way to copy a map is a for loop, really?
Apart from these, the language does make it easy for novices to write performant one-offs similar to how Python enables them to write slower one-offs. I personally hate writing in it, but I will when I think it makes my life easier.
Nothing to do with the language. Other platforms provide the same features.

Extremely verbose and also error prone. C#'s Tasks are much better abstractions for example.

Nothing to do with the language itself, it's just that it's compiled not interpreted like Python.
