Out-of-bounds access of array with or block doesn't return the value of the or block

[louis77]

Describe the bug

With an array with optional values (as used in the standard lib, db.pg for example), trying to access an item out-of-bounds with an or block, should return the value from the or block. But that doesn't happen.

Reproduction Steps

https://play.vlang.io/p/9326094f30

module main

fn make_option() ?string {
	return none
}

fn main() {
	arr := [make_option()]
	unwrapped := arr[99] or { 'unknown' } // <- out of bounds access!
	println('... ${unwrapped}')
}

Expected Behavior

should print: ... Option('unknown')

Current Behavior

prints: ... Option(none)

Possible Solution

No response

Additional Information/Context

The out-of-bounds access logic with or {} blocks for arrays and maps seems to collide with the Option/Result logic. Genereally it should be possible to have a shortcut for accessing an element in an array and unwrapping the element, if it is an Optional. Otherwise, the element must be assigned to a new variable first and then unwrapped.
