Hi Van,

My alerting readers to a relevant discussion for another language was not
intended as an attempt at language design nor as a solicitation for
proposals. I certainly have not “forgotten” your papers, and indeed I
indicated that the Golang discussions bore some similarity to proposals we
have seen.

J3 has not yet started actual design of an exceptions feature, which is why
I said they were “least well defined”. When J3 actually takes up such
design, which may or may not happen at 219, all the various papers to date
on exceptions, including yours, will be considered.

As an aside, and apropos of your second email, I at least am well familiar
with the Ada design, having been a developer/project lead on the VAX
Ada/VAXELN Ada project for five years and I spent a week with Jean Ichbiah
at Alsys Versailles in 1984. There are lessons to be learned from many
languages, including Ada. What makes the most sense for Fortran is yet to
be decided.

Steve
