[Hugs-users] A New Notation for Arrows

[Benjamin L. Russell]

Are there any plans to fix the preprocessor or update
Hugs so that scope errors or type errors will be
reported against the source code, rather than against
the preprocessor output?  That would render debugging
with new notation for arrows just as easy to
accomplish with Hugs as with GHC.
