I'm lost. A closure simply means it captures the local environment, right? So:
var y = 0
1 to 10 map {y+= 1; println}
println(y)
Now, I confess I am surprised that it appears this closure is called
once to get a function from Int => Any. I'm assuming it has always
been this way in Scala?
Of course, this does as expected, and looks similar.
for (x <- 1 to 10) {y+=1; println("hello")}
Is this is not a closure, as well?
