I've been waiting and waiting for someone to point out that
${i:s/foo/bar/} does work (and has worked for years and years), you
just need the final / (though I'm working on that, too), but no-one
has.  I can't believe no-one else knew?

Looking at the documentation, I can see the confusion:  it's mentioned
in the history section that modifiers also work on parameters, but not
in the parameter section.

We just didn't want to add noise to the discussion.  I've always used
${i:s/foo/bar/} and didn't really know about $i(:s/foo/bar) until this
discussion.  But finding out $i(:....) is good too, not that I'll ever use
it since I've been typing ${i:...} for years.  See, now you've just got
more noise on the list :-)
