$class is the same as $x (i.e. the bigint 27) the whole way through new, and bless implicitly stringifies its second argument (like print implicitly stringifies its arguments).

ref($x)->new(48) should do what you want. Another reasonably common idiom is:

my $new = (ref($existing) // $existing)->new(...)

This allows $existing to be either an existing object or a class name.
