The message I take from this is:
- regex engines certainly can be written to support streaming data; - but few of them are; - and it is exceedingly unlikely to be able to easily (or at all) retro-fit that support to Python's existing re module.
I don't know enough about the re module internals to make an informed guess about the difficulty. On a quick glance, it does seem to store most intermediate match state in explicit structs rather than on the call stack... -n
