During the latest SC meeting we discussed the fact that none of us felt we had a clear view of whether consensus was around pattern matching and the current PEPs exists simply due to the volume of discussion. As such we decided to create a poll to see what the general feeling was among everybody:

As mentioned in the poll, this is non-binding and mainly to help the SC understand if any form of consensus exists among ourselves. This poll will close in a week.
