Slices and Fixed Arrays

• fixed arrays [T; N]

• slices are just fat pointers

• &[T] is also a fat pointer, [T] is a managed slice, ^[T] is an owned slice

• [T] is managed by default (just like Function and Dynamic are managed fat pointers by default)

• subslicing: a range subscript is a view, not a copy — values[1..4] borrows a window of the backing store

• the view carries the receiver's access: a managed receiver gives a managed [T] view, &readonly/&exclusive give same-access borrowed views

• .slice() keeps its TypeScript meaning and copies; .toOwned() copies a view into owned storage

• values[1..4] = other copies in — lengths must match, elements must be Copy

• splitAt through &exclusive yields two disjoint exclusive views, both mutable

• a view keeps its backing array alive; owned slices ^[T] move as a whole and never split
