Rust – A hard decision pays off

I feel the same. Java and C# have an equivalent called 'var'. Unless the scope is tiny, I always avoid it. Also, in Java when you create a lambda, it is possible to exclude the parameter types.

    foo(x) -> get_something_complicated(bar(x))

It is not good for readability in large source bases.

With C++ lambdas, it's similar, but the syntax is a bit uglier:

  [](auto&& x) { return get_something_complicated(bar(x)); }

and you can decide whether you want a value (no &'s), an lvalue reference (&), or a forwarding reference (&&). I think with C++20 you can also use a concept instead of auto for a constrained parameter type.
