Is that actually guaranteed to release the string *right now*? I only ask because I seem to recall a message a couple of months ago about a more complicated object where it appeared that the initializer did a retain/autorelease on the object so it ended up in the autorelease pool before you even got hold of it. That was not an object obtained from a convenience method either IIRC, it was a [ [ SomeClass alloc ] initConstructorOfSomeSort ] call.

Unlikely the case with NSMutableString I'd think, but perhaps for other things.

The local autorelease pool version I'd think is guaranteed to work.
