If you got to remove one feature from #cplusplus, what would it be?
For me, comma operator.

So removing constructors would give you a _very_ different language. Some nice things would be lost, but I think overall you'd have something much better. So basically it's a sneaky way of getting a whole language redesign under the constraint of only removing 1 feature :)
Except destructors would still exist. So now copies and move ctors are gone and dtors are even more dangerous as a result.

Why would that make destructors more dangerous? It seems to work okay in e.g. Rust.

Suppose I have a class that contains a handle to a ref-counted object. When the class gets destructed I want to call releaseRef(handle). Without a copy or move ctor, I could easily call releaseRef() more times than addRef().
