It's a bit frustrating not to be able to catch
exceptions raised by re.compile with just the re
module. The fact that sre_constants.error is
raised is a bit too much implementation showing
through, IMO.
Anyway, I suggest a exception be added to the re
module that subclasses sre_constants.error for
backwards compatibility. So users can simply
import re and catch re.error instead of having to
import re and sre_constants and catch
sre_constants.error.

what Python version are you using?
