Subject: [ruby-talk:20747] how update anonymous classes?

Hi!

(1) What is the preferable way to add instance methods to anonymous
classes/modules?

(2) Are there ways to add instance methods to classes/modules without the
clumsy(?) eval "class #{KLASS}; def ..."

(I am implementing an experimantal system that will put the naming of the
classes/modules into separate functionality, not part of ruby itself. So
there will be no point in performing the normal "naming" of classes/modules.
It would seem a bir clumsy to do the naming anyway, and add all
functionality by eval, using some id-based naming scheme...)

(3) Is then the sensible (non-eval) way of doing this to put all forseen
functionality into prediefined modules and mix them in on-demand in the
already instantiated objects? Hmm or can I mix-in instance-methods into
classes without "eval"-ing?

Thanks for any help/hints!
