Dereferencing a none value silently crashes the program

[antoniusnaumann]

Currently, accessing fields from optionals that are none silently crash the program. I would have expected the compiler to give an error when dereferencing an optional.

When running this program

struct Node {
	data: i64
	next: Node?
}

mut list = new Node(data: 1, next: new Node(data: 2, next: none))
println(list.next.data)

mut list2 = new Node(data: 0, next: none)

println(c"ALIVE")
println(list2.next.data)
println(c"DEAD")

it outputs

2
ALIVE
