How do I create an attribute accessor to do this...

I want to be able to do this to merge a hash into attribute bas on
instance bar in class foo;

bar = Foo.new
bar.bas << { :this => "that" }

Is there any way to define the accessor in Foo to be able to do this?

Thanks,
James

class Hash
alias :<<, :merge!
end

class Foo
attr :bas
def initialize
@bas = {}
end
end

Is that what you had in mind?

Thank you both for such quick responses. I will give this a go tomorrow
