s[start:stop].find(prefix) No matter what, I really think the obj[start:stop:step] syntax needs to be consistent in its behaviour - either returning a copy or a view - Does it still matter if we're looking only at immutable sequences, such as text?

Actually, yes. I think it should be an explicit operation to say "I'm taking a small view of this large string, which will result in the large string existing until the view goes away".

Currently the way to do that is to have a method. I'm simply proposing that we reserve syntax that is currently not used to prevent it from being used for another, less appropriate usage. It may never be used at all.
