Hi, I've a class like this:

class Request
attr_accessor :method, :code
def to_s
"#{method} #{code}"
end
end

So if I print directly an instance I see a string containing both attribut= es:

message =3D Request.new
message.method =3D "INVITE"
message.code =3D "200"
puts message
=3D> "INVITE 200"

This is really nice but I'm not sure of how secure it's. Could
replacing "to_s" method change any other behaviour?

It's fine for your own classes.
