Testing your understanding of scoping (3)

This one's a little different. Instead of predicting what the function will return, you need to predict the value of a variable. We run the following in a fresh session in the console:

f <- function(x) {
  y <- 5
  x + y
}
f(5)

Now, what will typing y return?
