🤔 odd example for

!is

@Jonathan Mew You could ask a dog to meow, but he won't do anything 😄

You couldn't ask a dog to meow, there would be a compiler error

@Dico well according to the example, you can ask any animal to meow, which is why the example is odd 🙂

No,

meow

could be declared on

Cat

, in which case

animal

is smart casted to

Cat

. . .

if (animal !is Cat)

🙀

Well yeah, if it's you a cat you return and the second line never even runs. So by the time the second line actually happens you can be sure it's a cat.

Oh god. I've been reading it as

if (animal !is Cat) return animal.meow()

Thank you for saving me from myself. I'll go get some more sleep now.

Well then you've been reading correctly your code linewrapped for me, great.

Braces around if save animals
