I noticed a piece of code somewhere it does
NSMutableString *myString = [[NSMutableString string] autorelease];

Is it overkill? Shouldn’t it be the same as [NSMutableString string]?

    NSMutableString *myString = [[NSMutableString string] autorelease];

    will lead to a crash if they aren’t calling retain on it elsewhere.

    [NSMutableString string]

    is the same as

    [[[NSMutableString alloc] init] autorelease]
