Somewhat OT, but I think you should pick some other function than 
buildPath() for your examples.  It *used* to allocate east and 
west, yes, but that was a holdover from the old std.path.join().  
I made some improvements to it about half a year ago, and now it 
virtually never allocates more than once(*).

Note, this is not an argument against ScopeBuffer, which may well 
be very useful.  (I haven't looked properly at it yet.)

(*) Specifically, it will allocate more than once iff the list of 
path segments is an input range, and not a forward range, and the 
resulting path is longer than 255 characters.
