[racket] Making namespaces meet

Hi,

I'm having trouble of getting namespaces meet when making dynamic
definitions. I made a simple example below.

((lambda ()
   (define x 10)
   (eval (list 'define 'y 5))
   (+ x y)))

;>> reference to undefined identifier: y



I then tried to "store" one of the namespaces and pass it on to another, but
I guess that's not the way the namespaces work.



((lambda ()
   (define namespace (current-namespace))
   (define x 10)
   (eval (list 'define 'y 5) namespace)
   (+ x y)))

;>> reference to undefined identifier: y


Any ideas how to solve this?

br, jukka
