Foo.init must exist, and be filled with *something*.  Is it useful to  
FORCE buffer to not have 0 values?  Or is it that you don't care what it  
has?  In the latter, is it terrible that it's 0?

I tend to think that without the bar there, it could potentially be  
uninitialized (not sure if this is the case).  But as long as it's there,  
buffer must also be initialized.
