Well, that's fine, but that's a long way from Peter's statement that
"I think the tendency should be to get rid of E'' usage". It's only
been a minor inconvenience for me to change my applications to use
E'', but I certainly don't see how I could get by without it, and it's
far more like other programming languages that I use (e.g. C) than the
standard syntax is.
