Maybe not directly, but this might provide a starting point for building
such a beast:

    >>> import re
    >>> re.compile("[ab]", 128)
    in
      literal 97
      literal 98
    <_sre.SRE_Pattern object at 0x47b7a0>
    >>> re.compile("ab*c[xyz]", 128)
    literal 97
    max_repeat 0 65535
      literal 98
    literal 99
    in
      literal 120
      literal 121
      literal 122
    <_sre.SRE_Pattern object at 0x371f90>
