I developed some code in Hugs, but now am moving to GHC. I had used
Hugs because I wanted to use the Trex module (extensible records), but
this has not been as important as I had thought it would be.
My modules run fine in Hugs, but I get an error message when I try to
run my module in GHC. The message is:
parse error on input `PropList'
Otherwise the imported modules are interpreted.
In the module, the type declarations are:
type PropList = [String]
type World = Int
type Time = Int
type SOA = Rec (properties :: PropList, time :: Time,
world :: World)
type DBSoas = [SOA]
The error occurs just after PropList.
Is there some basic difference between Hugs and GHC that I'm missing?
Where can I get more information about Hugs GHC differences?
Cheers,
Adam
