> know how to capture arguments when needed
Not to take away from your other criticisms, but in most languages how the arguments are captured has no relevance (in Javascript — and most every other managed language — the environment is always captured by reference and the GC handles lifetimes of "whatever"), whereas it is very relevant and important for C++. So I think that part of the criticism is unwarranted.
Though Rust didn't go to the same lengths[0] you still have to specify whether the environment is captured by reference (the default) or by value (`move` lambdas), because that can have a large and semantic impact on the system.
