IO is always complicated:
I have never once thought it was complicated. All I've ever needed are
"print()" and "readLine()" and those shouldn't be complicated IMO. And I
wouldn't want to wait for page 120 to learn how to do that. My programs
are not going to be useful if they can't get user input or produce
output. I don't want to wait for page 120 to write my first useful program.
So I prefer starting a tutorial without IO,
interaction in GHCi and Hugs should be enough for the beginning.
GHCi and Hugs are enough for the /beginning/ yes, but that doesn't mean
that IO should go on chapter 7. How about putting it in chapter 2?
Cheers,
Daniel
