How is 

        $flag=1

clearer than

        POST{close FOO;&dropLock}

in this example?  I don't think the consistency issue is strong enough.
We are also being inconsistent by not suggesting a PRE which would be
analogous to BEGIN and would run at the beginning of a sub even though
it is defined halfway into it. For interior blocks, a label would
be used to say which block we're firing after.  Or we always use sub
blocks and that's that.
