Escaping... where? By "go with ref T" you mean return value of e.g.
front()?
Say front returns a reference to a first element in an array.
Say user stores &someArray.front as pointer somewhere, and the does
someArray.insert([1,2,3,4,5]);
In case array got resized the pointer is now dangling. Sealed containers
were meant to prevent such class of errors entirely.
We plan to disallow taking address of a ref return from a function.
