> (To be fair, there is one well-known foot gun, which is that if you lazily read from a file and close the file, the consumer of the file's contents will often get truncated results. So don't do that. Maybe it's been fixed by now, or that API's been deprecated? I haven't really kept up on current events in the Haskell world.)

I think the API is still there, but lazy IO is so heavily discouraged that no one is using it. It's not relevant anymore and considered a mistake.
