Any addition raises the barrier-to-entry. If you don't have any
technical objections, you should really stick to "degree of change
you're requiring in currently sanctioned and common C++ code might
reasonably be judged to be beyond the bounds of proper evolutionary
change for an existing language with a moderately long history of
fairly wide use" (source: DRB) line of reasoning in opposition to
2-phase EH. Unconvincing and highly subjective, if you ask me.

2-phase EH can be based around "not a very naive" setjmp/longjmp-
like mechanism, I think.

P.S. Isn't "export" a much more severe barrier-to-entry? ;-)
