Ask an easy question and you'll get at least a dozen people tripping 
over each other in their rush to offer you useful advice. Ask a hard 
question, or an uninteresting question, and enjoy the utter silence... 
:-( Still, I suppose that's not *too* surprising.

I used to use Hugs as well. Then I updated to the newest version, and 
found it horrifically buggy. That's when I moved over to GHC. As Don 
said, GHCi doesn't let you define new functions like Hugs does, but 
other than that it's far more useful. (And actually, you *can* define 
small functions using 'let'. It's just awkward.) Best thing is, you can 
compile your code with GHC, and then load that compiled code into GHCi 
so it runs at near-native speed. And of course, the latest version of 
GHCi now comes with an actual debugger. And GHC-compiled binaries have a 
profiler. And...

[This was a while ago; maybe Hugs has been updated again since I last 
looked. Certainly Hugs is smaller to download, and more friendly to use 
than GHC. But it just doesn't have the same power...]
