The easiest equivalence is that essentially everything in Ruby is a 
pointer and the . operator in Ruby is the equivalent of C++'s -> (This is 
similar to how Java behaves as well.) The = operator changes where the 
pointer points.

There's no such thing in Ruby as a pointer to a pointer, nor is there any 
such thing as a variable that's not a pointer at all.
