That's right - there seems to be a slight bug in Simon's example on
the web page, which just goes to show what a sticky issue layout is.
I think the correct example is
do
putStr "hello"
if .... then
putStr "goodbye"
else do
putStr "carry"
putStr "on"
the point is that the 'else' needn't be indented. This would be
possible too:
do
print n
putStr " green bottle"
if n > 1 then
putStr "s"
else
return ()
putStr " sitting on a wall"
Cheers,
Simon
