Again the release is very nice!

A question: I seemed to miss the scope guard discussion (whatever). Can you
enlighten me with an example (or guide me with a link) to illustrate the
usefulness of this feature?

Thanks,

P.S.: In the new docs for the scope guard stuff there is a TYPO at "[snip] close
of the scope, they also are interleaved with the OnScopeStatements in the
reverse *lexeical* order in which they appear."
