Python can serialize ('pickle') compiled regular expressions, and python
interfaces well with C.


e.g.


import re, pickle


r = re.compile("foo|bar|baz")
fid = open("regexp.file","w")
pickle.dump(r,fid)
fid.close()




fid2 = open("regexp.file","r")
reg = pickle.load(fid2)
fid2.close()


print reg.search("afooa").group()






Cheers,
Carl.
