Description

Example 3 is problematic and potentially invalid.

// Iterate over partially initialized ranges
//
var integer e, i := 0;
for (e in {1, -, -}) {
    i++;
}
log("final value:", e);
// Output:
// 0
// 1
// 2
//final value: -

It should be replaced by something less controversial:

// Iterate over partially initialized ranges
//
var integer i := 0, e := 0;
for (e in {10, -, 30}) {
    log(i, e)
    i++;
}
log(i, e);
// Output:
// 0 10
// 1 UNINITIALIZED
// 2 30
// 3 30
