Oh ok. It seems like we use PyList_xxx() functions, so yeah, it seems safer (to respect the Python semantics) to only accept exactly the list type.


> Updated patch restricts _sre.compile() to accepting only exact collection types. I don't like this patch.

Why not? Do you prefer to accept subtypes?

sre-concrete-2.patch LGTM, I just added a minor comment.
