Subject: Re: how to create a method object of from an singleton method?

Not sure if the ruby docs aren't clear enough.


Look into define_method, class_eval and instance_eval. It will be one
of those or higher ordered scoped where singleton_ is before them. Of
course you can always user eval primitive or monkey patch it all the
same.
