[Simon Peyton-Jones]

Good point. I've done this. (Ian, could you merge)

  * Allow the old [$foo| ... |] syntax for quasi-quotes
  
  This is just a backward-compatibility thing, to be removed
  eventually.

| Sorry, maybe I missed the memo on this one, but I just noticed this
| change to quasi-quotation syntax on the GHC 7 upgrade page[1]. So if
| GHC 6.12 *requires* the dollar sign, and GHC 7 *rejects* the dollar
| sign, is there any way to write code that will run on both? Is there a
| reason we can't keep the dollar sign as supported syntax for a release
| or two to make for a cleaner migration?
