That the alternative destructor runs only when you ask it to. 
There would be some way to say before an end of a block, return 
statement, break statement ect that you want the alternative 
destructor to be applied to the struct.

The normal destructor would not run when an alternative one is 
used, but would run otherwise.

In fact, in this case it would be enough to elide the destructor 
somehow.
