Yeah. That was just another in a very long chain of super clever ideas in that talk. I'm nowhere near a hardcore enough perl hacker to understand most of what she said, but I caught enough for it to totally blow my mind.
My favorite bit was when she put up the IRC quote of Larry calling perl scary. He was in the audience of the talk, shaking his head almost the whole time :)
With the limitations, I'm almost tempted to say she should have put it in Acme:: (where joke modules go, by convention). It's worth noting that the <...> syntax for glob() has long been considered a bad idea to use in actual code; it tends to make your code more difficult to read then it's worth, because <...> is also a shortcut for calling the readline function on a filehandle; the difference between them, when parsing, is somewhat obscure, and I'm amazed Audrey's hack works as well as it seems to.
Oh, forgot to mention. This was inspired (in behavior, not implementation) by Erik Meijer's stuff: look for HSP, which I think used a preprocessor/source filter, and Visual Basic 9 which has it in the language.
