DIP44: scope(class) and scope(struct)

[Meta]

"With this extension to scope guards, class and struct 
destructors will practically not be needed anymore, since 
scope(this) will take care of cleaning up everything."

I can't think of an example off the top of my head, but is it 
really okay to conflate destruction due to an error during 
construction, and destruction over the regular course of a 
struct's usage? What if one instance requires different code from 
the other? Maybe require that scope(this) statements *only* be 
run if there is an error during construction, while just the 
destructor will be run normally?
