[swift-users] read data from the code

I couldn't figure out a way to bring back line numbers but here's READ and

// Define your data

let DATA = [5,7,1,6,7]

// Change the Int below to whatever type of DATA you have

let READ = {() -> () -> Int

    in var g=DATA.generate();return {()in return g.next()!}}()

// And now you read

print( READ() )

print( READ() + READ() )

print( READ() * READ() )

It's like magic and stuff.
