For one use reread the OP's node. I frequently use the technique when answering SoPW's where an input file is required. I could write a temporary file then use that, but that adds clutter to the sample.

In real applications I've used the technique to cache parts of a file that I need to access frequently and to provide a file handle for modules that require them when I really want to pass in a string.

True laziness is hard work
