     1.6  expand them automatically.  Definitions are intended for introducing abstract
     1.7 -concepts and not merely as abbreviations.  (Contrast with syntax
     1.8 -translations, \S\ref{sec:def-translations}.)  Of course, we need to expand

    1.11  of the new constant, we can forget its original definition.  This style makes
    1.12  proofs more robust: if the definition has to be changed,
