[J3] Exception handling - Golang proposal

[Steve Lionel]

One of the major features we've said we'd like to see in F202X is 
"exception handling", but this is probably the least well defined (for 
Fortran) of any of the features proposed. Tonight I ran across a 
proposal being suggested for the Go language which bears some 
similarities to at least one proposal I've seen for Fortran. Some in the 
Go community don't like it.

I haven't studied it enough to see if there are any "take-aways" for 
Fortran, but I found it worthwhile reading as I saw echoes of some of 
our earlier discussions.
