In Ruby, is there no way to dynamically define a local variable in the current context? [duplicate]

Answer 1

Would a class instance variable work for you?

class Cat
end
Cat.instance_variable_set '@last_words', 'meow, meow, me...'
Cat.instance_variable_get '@last_words' # => "meow, meow, me..."
Cat.new.instance_variable_get '@last_words' # => nil

If not, please elaborate on the context and how you would use the local variable.
