However, if you want an un-adorned object later, just use infix:<but>,
and keep the original object around.
class C {
has $.name = "original";
}
role W {
method name { "wrapped" }
}
my $original = C.new;
{
my $wrapped = $original but W;
say $wrapped.name; # "wrapped"
say $wrapped ~~ W; # True
}
say $original.name; # "original"
say $original ~~ W; # False
// Carl
