# PYPY Modification: removed the EMPTY class as it's not needed here
-# PYPY Modification: we don't need a particuliar DEFAULT class here
-# a simple None works fine.
-# (Having a DefaultClass inheriting from str makes

-DEFAULT = "\00default" # XXX hack, the rtyper does not support dict of with
str|None keys
- # anyway using dicts doesn't seem the best final way to
store these char indexed tables
+# PYPY Modification: DEFAULT is a singleton, used only in the pre-RPython
+# dicts (see pytokenize.py). Then DFA.__init__() turns these dicts into
+# more compact strings.

# PYPY Modification : removed all automata functions (any, maybe,
# newArcPair, etc.)
