Interesting.
Didn't know you had written a module like that.

Yes indeed. their "defer" mechanism gets to be catch blocks as an
extra thing. I wonder if the Go compiler treats recover() specially to
optimize happy paths. It certainly could.
Go is the first compiled language I've seen with "Yoda's exceptions"
as discussed thirteen years ago on
the perl six development lists. They recommend against using them, and
didn't even bother to suggest repanicking with the received exception
after recovering an unexpected panic topic. Which is obvious to
anyone who likes exception-based control flow, so no hard feelings. I
like the way that the "defer" keyword, which is like on_exit from CPAN
(my version works better! prefer local$on_exit, it will continue to
work right even if garbage collection starts getting deferred) doubles
as "catch."

I think the go approach is pretty interesting.
Seems to create some other possibilities besides just error handling.
