The impossible happened

[Simon Peyton-Jones]

Aha. You have a "\" in your rule name.  That doesn't work in
5.02 for tiresome reasons; it's ok in 5.04

thanks for the clear report

| Hi,
| 
| GHC gives me this message when compiling with the -O flag (it 
| doesn't happen without it):
| 
| ghc: panic! (the `impossible' happened, GHC version 5.02):
|         Rules/Deprecations parse failed
|     ./staticanalysis/Constraints.hi:63: error in character literal
| 
| Please report it as a compiler bug to 
| glasgow-haskell-bugs at haskell.org, or 
| http://sourceforge.net/projects/ghc/.
| 
| The platform is 
| Windows 2000. "Constraints.hi" is attached.
| 
| Greetings, Arjan
