I have listened. I have updated.

// Types
MemoryLayout<Int>.size // 8
MemoryLayout<Int>.arraySpacing // 8
MemoryLayout<Int>.alignment // 8

// Value
let x: UInt8 = 5
MemoryLayout.of(x).size // 1
MemoryLayout.of(1).size // 8
MemoryLayout.of("hello").arraySpacing // 24
MemoryLayout.of(29.2).alignment // 8
