I'm thinking that an early 2020b release would be good, to

In that context, I think most of the changes since 2020a are harmless, with
the possible exception of the modification of funcerr(), so I'd like to
revisit that.
Quick recap:
[...]
Here are my second thoughts. Usually when we offer a function version
of a
command it's just a matter of adding convenience, for users comfortable with
function calls, with no change in semantics relative to the command. That's
true of the first version of funcerr() but not the latest one. So my latest
change is kinda unruly.
If we were willing to add a new function we might call it "iferror", as in
iferror(error_condition, message)
This would work just like the new funcerr(), but funcerr() itself would
revert to its usage in 2020a, parallel to the command. Any thoughts?
I think this is cleaner. Eventually, we can deprecate the function form of
funcerr() and retire it (clearly, in due course).
