How can I do something like the following:
class Foo
attr_accessor :goo, :moo
def initalize
@attr.each { | attrib| attrib = 0 }
[:goo,:moo].each { |sym| send "#{sym}=", 0 }
or:
[:goo,:moo].each { |sym| instance_eval "@#{sym} ||= 0" }
end
end
You have to specify the variable names. Ruby only creates an instance of
the variable once it's accessed.

You could also use: instance_variable_set("@#{sym}",0)
(which might be more self-documenting).
