Quasiquoter invocation no longer requires/allows a leading dollar sign.
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?

Good point. I've done this.

Thank you very much. I was dreading the thought of figuring out some
CPP hack to accomplish this, and applying it across my codebase. Much
appreciated!

Thank you very much for this! I was afraid to see so much code broken as well as Michael. Best regards, -- Nicolas Pouillard http://nicolaspouillard.fr
I'm guessing this did *not* make it into 7.0.1, correct? Is there
still a chance that it will be in 7.0.2, and therefore the next HP
release?
