Storing a function result value in a variable does not work as expected in an or block

[ttytm]

Describe the bug

Storing the result value of a function call in a variable behaves differently than directly passing the function multiple times.

Reproduction Steps

No variable usage, expected result:

fn str_ret_fn(str string) string {
	return str
}

fn foo(str string) !string {
	if str.contains('foo') {
		return str
	}
	return error('error')
}

var := foo('bar') or {
	// foo_var := str_ret_fn('foo') // uncomment for unexpected behaviour
	if str_ret_fn('foo') == 'foo' {
		foo(str_ret_fn('foo')) or {
			eprintln(err)
			exit(1)
		}
	} else {
		eprintln(err)
		exit(1)
	}
}

println(var) // `foo`

Variable usage, unexpected result:

fn str_ret_fn(str string) string {
	return str
}

fn foo(str string) !string {
	if str.contains('foo') {
		return str
	}
	return error('error')
}

var := foo('bar') or {
	foo_var := str_ret_fn('foo')
	if foo_var == 'foo' {
		foo(foo_var) or {
			eprintln(err)
			exit(1)
		}
	} else {
		eprintln(err)
		exit(1)
	}
}

println(var) // `println(NIL)`

Expected Behavior

No difference weather using a variable or not.

Current Behavior

See repro above.
