Looks like their is still a problem with implicitly fixed variables in 
locale expressions.  It appears to work if you make the binding of "init" 
explicit in locale r1, using the 'for' in postfix notation:

locale r1 =
   r0 "init :: 'buffer => ('buffer \<times> 'value) set => 'value" for init
   + fixes d2i :: "('buffer \<times> 'buffer) => 'buffer"
