Does it? As far as I know, the mechanisms are exactly the same,
even though the syntactic expression is different. I wouldn't
characterize C++'s way as a particular advantage, notwithstanding
the (snipped) argument below.

Threads are not part of the Standard, but when implementations
support them, I believe exceptions work correctly, and don't
interfere with other threads.

And arguably better than Ada's version.

Fortunately, this has just become no longer true. The compiler sold
by Comeau, featuring a front end created by the Edison Design Group
and a library built by Dinkumware, now supports Standard C++ in its
entirety.
