[swift-users] Struct lazy Variable doubt

I am a little odd about it too.

However,  if you give it a try, you will get the results.

var lazyStruct = lazyTest(lazyVariable: 5, someProperty: 6)

lazyStruct.lazyVariable // 5


var anotherStruct = lazyTest(lazyVariable:nil, someProperty: 7)

anotherStruct.lazyVariable // 10


‚ÄčEverything works fine.‚Äč If you give it a value, it just ignores the lazy
part. If you give it a nil, it works as you expect.

So initializer of Struct just adopts to a more flexible way, I think.
