C++ has a finally equivalent in a different form: Every object gets to clean up at the end of the scope as part of it's destructor. If you're not using RAII to manage cleaning up resources at the end of a scope, it's probably a good idea to change your style a bit.
It is definitely great. Although missed this for quite some years now, it is quite pleasing to see how the language continue to evolve throughout the years :)
But it's great to see half-complete features becoming fully complete, even if a few years late.
