Type requires no arg constructor

Nowhere in the documentation it mentions that the type T must have a no-arg constructor for this to work.

Please specify in the documentation explicitly, otherwise figuring it out may cost a lot of time to the developer like it did for me.

No documentation file is named in the issue. Start by locating the documentation that explains the required type T and review how constructors are described. Done means the documentation explicitly states that T must provide a no-argument constructor for this usage.
