+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)
