GCC's statement expression extension

[Richard Kenner]

    Speaking for the users, I would argue that removal of statement
    expressions, even in C++ only, is a supremely bad idea.  I would
    hesitate to guess how many people use these features right now, but I
    would be willing to bet it more than the people reading this mailing
    list.  Misdesigned or not, it is an incredibly useful feature, and
    people use it.  Even if there are better ways of doing it, won't
    change all of the extant code out in the world.  

I *strongly* agree
