method = 3 will always assign to a local variable.  If you really want 
to produce other side effects you need to do

self.method = 3

The topic seems to come up more frequently in recent time.  I don't know 
whether Ruby community experiences increased migration from C++ 
developers or what the reason for this is.  I believe the fact that 
people search for something call by reference in said language indicates 
that they do not have adjusted to the Ruby mindset yet.  Shea, if you 
provide more context we might be able to help you understand how the 
problem you are trying to solve is usually solved in Ruby - without call 
by reference.

Kind regards
