[Haskell-cafe] Bug in WinHugs?

[Lyle Kopnicky]

Hi folks,

I just installed the May 2006 release of Hugs. When I use the 
command-line version, the '$$' symbol to reference the last expression 
works fine. It does not work in WinHugs, but yields 'ERROR - Syntax 
error in expression (unexpected symbol "$$")'. I typed ':set' to verify 
the '-r$$' option was set properly.

Is this a known bug, or am I doing something wrong?

Thanks,
Lyle
