The `with` construct is good, but it could be great

One of the big usage of "with" in C# is that the destructor (on 
the class that is in the with expression) is guaranteed to be run 
when it leaves the scope. C# is similar to D that you don't know 
when the destructor is executed but the "with" statement makes it 
deterministic.

Does D need a "with" statement? I don't know and it also depends 
how the libraries are written. I'm personally not completely 
against introducing "with" in D. D has tried to follow Rust 
lately but I rather see that D follows C# as it is a better fit.
