Record

The binding of a record node, such as a case class. constructor builds a value from Registers, and deconstructor writes a value's fields into them.

Both must use the layout that Reflect.Record#registers computes from the node's fields. In field order, a field stored as a Boolean, Byte, Short, Char, Int, Float, Long or Double takes the next position of its size in the byte area, a Unit field takes no space, and every other field takes the next object slot (see Register). Reflect.Record#fromDynamicValue and #toDynamicValue move each field through that layout, so a binding with a different layout reads the wrong registers.
