There's a lot of $. (<-- that dot is a regex =]) variables to love, yet I've only stumbled across a few of them, and even less explanations of what those variables do. Anyone know of a comprehensive listing of what variables are available to us in the $/./ (<-- that is a correct regex!) format and what they all do? I haven't noticed it in any of my books (I haven't read all of every book yet, so standard disclaimer of "i may be a fool" applies here).
