Hi Albert, Thanks for spotting this, it definitely looks wrong. On the line above I also see the ^ characters have got corrupted. I've emailed it onwards to the current report editor (Malcolm Wallace) Thanks, Neil On Thu, Mar 17, 2011 at 4:57 PM, Albert Y. C. Lai <trebla@vex.net> wrote:

Haskell 2010 report chapter 9 Standard Prelude uses a wrong backquote, e.g.,

infixl 7  ⋆, /, ‘quot‘, ‘rem‘, ‘div‘, ‘mod‘

Those are U+2018. The grammar (Chapter 3) requires U+0060 and accepts no substitutes, e.g.,

varop → varsym | `  varid `
