Thanks,
That fixed the load error, but there is still a problem with the to_yaml=20
routine. The additional @size parameter never gets written to the YAML=20
string.

require 'Yaml'

class Box< Array
def initialize size
@size =3D size
end
def size
@size
end
end


box =3D Box.new(2)
print "ERROR: Box, #{box.size}!=3D2" unless box.size =3D=3D 2
box2 =3D YAML::load(box.to_yaml)
print "ERROR: Box2, #{box2.size}!=3D2" unless box2.size =3D=3D 2
p box.to_yaml


ERROR: Box2, !=3D2=20
--- !ruby/array:Box []=20


Any ideas?=20
