Oh, I know what Bblocks are. We even have B::Bblock to detect them!
I was just trying to work out whether they'd always be related to
scope, because I forgot about things like

    if (,..) {
        } # ends basic block and scope
    # starts basic block but not scope

There is a strong correlation between bblocks and scopes, and you can
easily derive one from another. But it took me a while to remember that
they ain't the same. :)
