This is more-or-less what I was asking about several weeks back on the
"boost-users" list (although at the time I didn't know how to require
the semicolon - I do now, thanks to the feedback.)  

As others have
pointed out, it's more convenient in many ways, and IMHO more
"natural" to have the semicolon.
