Remember A as forty-two
   Tell me about A
   Remember B as A
   Tell me about B
   Remember C as B
   Tell me about C
   Remember D as C
   Tell me about D
   Remember E as D
   Tell me about E

   Remember F as E

Another neat thing to try is:

   Remember x as zero
   Remember y as x
   Remember x as y

Fun fact, if you run Python from a command line, with no options, it defaults to such a shell.

On another note, I do not understand how posts make it to the top of the front page with essentially no comments.
