I wouldn't think such (and don't =). The two weren't intended to
directly relate; I apologize for causing you to infer otherwise. =]

The first paragraph you quoted relates to benchmarking I'd done some
time ago (mentioned in a portion of the same posting not included in
your quotation of it). The second bit you quoted relates to the bit of
Mark Harrison's original posting (also quoted in my original post)
regarding there being "the same feeling as in C++ that exceptions can be
used for non-error situations".

Sorry for the confusion!
