Of course methods need local variables, but blocks would have local  
variables still, just all in the scope of their defining method. Why  
do closures need to have their own, unique variables outside of the  
scope that they enclose? Smalltalk gets along quite well with all  
blocks sharing the same local variable scope. The current scope rules  
are a problem for a lot of new ruby programmers. Lots of them see the  
current behavior as a bug that they have to work around.
