Hi,

If I'm understanding the definition of stable here, it means that if two values
evaluate to equal they will always end up in the same order in the output that
they were in the input, yes? So (trivial example):
$a = ["3", 2, 3, 5];
Sorts to:
[2, "3", 3, 5];
always, whereas right now it may sort to that or to [2, 3, "3", 5], somewhat
randomly. Am I understanding correctly?
(That is _my_ understanding, though I'd take Nikita's word for it rather
than mine.)
I think you indirectly point out a good reason to have a stable sorting
algorithm for PHP: PHP's weird type-juggling equality rules mean several
kinds of values that are not really (===) equal will compare equal (==)
so far as sorting cares, which probably means messy results sometimes
when paired with an unstable sort?
Thanks,
Andrea
