Shouldn't that be ==:/ (maybe the "severely startled muppet" operator?
lol...) A single = would be assignment, but I have no idea how
adverbial modification would affect that. Exactly what *would*
adverbial assignment be? Would
$a =:\ $b
be like
$a = \$b;

Is that saying to make budgetwise the comparison operator at the same
precedence as eq?
Wouldn't that be much like saying
my sub infix:um (Int $a, Int $b) is equiv(&infix:eq) { # c.f.A6 p.11
-1_000_000 <= $a - $b <= 1_000_000; }
if ($log_rolling um $pork_barrel) # etc
So how does one get a ref in P6 that won't dereference itself???
The we could say
my sub infix:embodies ($a,$b) is equiv(&infix:eq) {
$a.ref eq $b.ref # unless eq deref's even here.....
}
if ($x embodies $y) {
print "X and Y refer to the same entity\n";
}
