Bytes of the PNG, or of the raw pixels?

How is this [nesting] behavior implemented under the hood?
Pointers.
And why is this allowed at all?
There's no reason not to.
There's no reason not to allow it with tuples, but you can't do it.

Is that true? Does WriteConsoleW support every Unicode character? It's

If this is a bug, maybe it is one in type() itself - I get the same
