How to write inline if statement for print?
...ents. Only the a part is an expression. So if you write
print a if b else 0
it means
print (a if b else 0)
and similarly when you write
x = a if b else 0
it means
x = (a if b else 0)
Now what would it print/assign if there was no else clause? The print/assignment is still there.
And not...

Yes you can. You can even test it:

When is memoization automatic in GHC Haskell?
...situations. For example, consider the function
f = \x -> let y = [1..30000000] in foldl' (+) 0 (y ++ [x])
GHC might notice that y does not depend on x and rewrite the function to
f = let y = [1..30000000] in \x -> foldl' (+) 0 (y ++ [x])
In this case, the new version is much less effici...
