Curly braces vs. do/end in code block syntax

The difference between the two ways of delimiting a code block is a difference in pre- cedence. Look at this example, and you’ll start to see how this plays out:

array = [1,2,3]
  => [1,2,3]
array.map {|n| n * 10 }
  => [10, 20, 30]
array.map do |n| n * 10 end
  => [10, 20, 30]
puts array.map {|n| n * 10 }

countZeroes :: [String] -> Int
countZeroes = sum . map length . map (filter (=='0'))

countZeroesAgain :: Show a => [a] -> Int
countZeroesAgain = countZeroes . map show

-- and for the one line, because I guess that's the challenge
-- btw, it's type is
-- cz :: Show a => [a] -> Int
-- which means that this function works any list of things that can be printed

Well, I've certainly been on the lookout for leggings.

I told myself this as I entered the small clothing shop on 14th St. It was a Saturday afternoon in Union Square when I spotted the rack of navy, brown, and black. '$3.99' was scrawled in cardboard. I chose a pair in black and headed toward the register to pay.

The second I stepped inside I heard her voice. An older Asian woman, perhaps in her fifties, held a phone to her face and manned the register in the back. She spoke in loud and brusque Korean, sans affectation. I imagined she was talking to her sister on a different continent. Or an old friend.

Or a daughter.

As I brought the pair of leggings up to the counter her voice lowered slightly in acknowledgement. Polite, I noted. She held up four fingers. I reached for my wallet, and waited for the questions that would inevitably follow.
