Aren't local variables also local to the scope where they are set?  In 
other words, what defines a scope in ruby?  More specifically, how do 
you know the extent of $1's scope?

In my last example, the each block seems to define the scope of the 
'name' variable.  Why doesn't the each block also define the scope of 
the $1 variable--after all the match occurred inside the each block?

Thanks.
