Surely I can get along without getContents in WinHugs: last time I thought
it I just wanted to show getContents function to my students (and using
on a file handle seems to be better example). Another function that
could be useful when teaching IO is 'interact', and it seems that it's also
impossible to use it without typing EOF (am I right?).
So it would be nice to have a way to type EOF in WinHugs, but surely it's a
feature one can live without.
And thank you for WinHugs, it is really useful!
