Seems unlike that it would expand you space very much. Every function  
you create will have an environment.

You need to demonstrate what "tree" structure you propose to populate  
and then access. Since tree's are not an R data type, you should show  
us _exactly_ how you will create one, presumably using "lists". Once  
you have a small example it is very easy to present by using the  
output of the 'dput' function.

You should also realize that you are probably limiting your audience  
severely by not posting context. Most people do not read Rhelp on  
Nabble.
