class ObjAt

Unique identification for an object

class ObjAt { } is Any

Objects of type ObjAt are the return value of .WHICH calls on other objects, and identify an object uniquely.

If two objects compare equally via ===, their .WHICH methods return the same ObjAt object.

See also ValueObjAt for value types.


infix eqv

Defined as:

multi sub infix:<eqv>(ObjAt:D $aObjAt:D $b)

Returns True if the two ObjAt are the same, that is, if the object they identify is the same.

my @foo = [2,3,1];
my @bar := @foo;
say @foo.WHICH eqv @bar.WHICH# OUTPUT: «True␤»
