I'm not an expert on D but Google tells me that it doesn't support
automatic deterministic termination. So, if you have a file or a
handle open, you need scope(exit) to close it. It also means that the
programmer must keep track of all non-memory resources and dispose
them "manually" like a C programmer.

In C++, RAII makes scope(exit) unnecessary, and catch(...) is the same
as scope(failure).
