Are we ready for

  @x = 1

  a = "x"

  @{a} #=> 1

Not me, but how about:

     container@[index]

as sugar for:

     self.container@(index)

and

     container@[index] = val

as sugar for:

     self.container@=(index, val)

As a degenerative case you could omit the 'container':

     def @(index); end
     def @=(index); end

PHP-style "variable variables" just lead to code that is too clever for its own good. Using a Hash is a much more readable solution.

Perhaps so. And I am presently working on such code. BUt to be honest,
I haven't found a more reasonble way to handle it. As it stands I have
to do instance_variable_get/set or eval the whoe method def.
