Regarding q{} and qq{}, I am from a *nix background and had never had any problem with normal single- and double-quotes. Then I started trying to do one-liners under MS Windoze and struggled. The quoting operators made it all work nicely and since then, to avoid having to think where I am, I have got into the habit of using them all the time. I don't think that there is any particular merit either way other than normal quotes are widely familiar and take fewer keystrokes, quoting operators do the right thing at the DOS prompt.
Cheers,
JohnGG
