Would you also propose to rename the scope_final class template? What
name would you suggest?

Interestingly, there seems to be a proposal to add `defer` to C:

https://www.open-std.org/jtc1/sc22/wg14/www/docs/n2895.htm

So I guess, we should avoid taking the word `defer` in case it becomes a
keyword some day.

I'm not opposed to renaming, as long as the new name is short and not
misleading. I'm not familiar with Go (presumably, from which the name
comes), so I can't tell how similar the semantics of the feature in Go
is to the proposed library.

FWIW, in BOOST_SCOPE_FINAL, "final" is partly a reference to
`__try`/`__finally` in MSVC and `try`/`finally` in Java, and partly
emphasizes that the scope guard is "final" after construction, i.e.
cannot be modified or cancelled. It also reads almost like "finale of
the scope". I like it.
