I tried to write a snippet that would be detected at compile time, but was unable, apparently due to my PHP engine's interpreted nature. The creator(s) should have provided a usage example (for end-users) or pointed to PHP sources for an example of where/how it's used. None of the provided examples, to date, reflect an exception detected at compile time, as this class asserts.

IMO it's hopeful at best to expect a compiler to detect an illegal index in a dynamically-typed, typically JIT-executed, enviro. Since when is there a strict contract of what indexes should be considered "within range" and how would the compiler know about this contract? Also, how would we try/catch that in the compile phase?

SPL also provides the OutOfBounds exception. If this class, its parent, and OOB have little distinction, then does SPL need all 3?

I see this in this way:
By definiton, OutOfRangeException should be use to when potential problem is logical - occurs because of wrong code or definition. OutOfBoundsException is for runtime.

Example (see also note in "OutOfBoundsException class" article):
<?php
function prepareData(PDOStatement $s) {
   
$x = $s->fetch();
    if (!isset(
$x['secretColumn']))
        throw new
OutOfRangeException ("Secret column doesn't exist! Verify table definition and query.");
}
