 * performance issues
 ************************************************************************
 
 Several areas can be cleaned up to make mandoc even faster.  These are 
 
-- improve caching mechanism to handle other per-element arguments so
-  that they need not be recalculated between front- and back-ends (also
-  reduces code size and complexity):
-    `Bl -column' pointer
-    `Bf' font type
-
 - improve hashing mechanism for macros (quite important: performance)
 
 - improve hashing mechanism for characters (not as important)
