You probably knew this already but there's nothing in the "with idiom" that prevents the resource to escape.
And, it doesn't always matter. Some withs are more unsafe that others :)
if the 'with' constructs a nice ordinary heap allocated haskell structure from the external resource then it may not matter one jot if it escapes: it may be out-of-date, perhaps, but still a useful data value.
I'm sure you're right but at the moment I can't really think of any such structure. Perhaps you could give an example? Why would you need the "with" in the first place for such a structure? Cheers, Johan
