When I read crystal source, I find many unfaimilar features.

then we create another C++

You may be right on the stdlib scope, there is a RFC about shrinking it.
Surprising features, yes it might, but unfamiliar depends if you are new to the language. This would be quite normal.

#4

forall T?

#5

It’s just another syntax for specifying generic parameters. Other languages use void Foo<T>

I would disagree with this, I feel a lot of other languages have way to much bloat, vestiges of the past that were great in the beginning but became a less expressive way to write code over time. Things like for, foreach, etc. Ruby/Crystal removed a lot of that kind of bloat for things that are much more expressive, like #times, #upto, #downto, #each. IMO opinion, the basic syntax of Crystal/Ruby is smaller in it’s scope, but much more powerful and expressive than other popular languages. The reason that I use Crystal is because I know it won’t become a language like Java or C#, syntactically bloated (look at C#'s dynamic and tell me that was a good idea), with features that are niche, not commonly used, and probably done in a better and saner way.
