Well, str.replace has a count parameter.  Presumably people use it (even if by accidentally discovering that without it, it replaces all occurrences when they only wanted one replaced).

Just the first occurrence. The vast majority of the time, that's what people want to do, and they will usually forget to add a 'count' parameter. Many people probably wouldn't even know it exists. It would be disastrous if code did the correct thing 99.9% of the time but occasionally silently mutilated a string.

Should `-+-+-+Spam'.stripprefix('-+')  remove just the first occurence? 
All of them?  Does it need a 'count' parameter?

[all modulo bikeshedding on the names of course]
