worksFine =
if True
then putStrLn "True"
else putStrLn "False"
worksNOT = do
if True
then putStrLn "True"
else putStrLn "False"
worksAgain = do
if True
then putStrLn "True"
else putStrLn "False"
Of course the worksFine function returns an IO action, so has different
behavior, but I mean the indentation is different. Is this by design?
Also the following is rather strange:
doubleDefError = let x = 1
x = 2
in x * x
alsoDoubleDefError = do
let x = 1
x = 2
return (x*x)
doubleDefNOERROR = do
let x = 1
let x = 2
return (x*x)
Now I understand why this is (the second let starts a new invisible
scope no?), but for newbies, this is all very strange :-)
Cheers,
Peter
