A good point certainly... I suppose it could continue to follow the
current form, evaluating $c as false and return int(1) instead of
bool(true). Though that would probably diminish it's utility for 'if set
or'. And there would be a BC break for those doing:
$a = $b || $c;
if ($a === true) {
}
But anyone doing that should probably have their head examined.
Anyway...
Regardless of what can be said about changing the behavior of '||', the
same isn't true for '||=', as it has no precedence in PHP.

One already understands the idea of 'this || that'. It's certainly
I'll throw the water on this one:
<?php
$c = 0;
$a = 1;
var_dump($c || $a);
?>
With the existing PHP, this script results in:
bool(true)
With your proposed change because it would return the first non-null set
variable, it will instead output:
int(0)
Changing true into false consitutes a rather severe BC break :).
