in reply to Glob strange behavior

Can someone actually explain this? why glob in scalar context will return undef for every other file? The documentation says in scalar context glob returns an iterator(which is ok, so one can do a while loop to go through all of them). But why does it fail for every other file? I thought it might be some side effects on $_, but that's not. Thanks.
