hm,... but is there a problem to think of reference in Ruby as a 
"pointer"?  will that cause any trouble?   I only see that  a.value  is 
not the same as C and C++ would use a->value, but in Ruby we use the "." 
to replace the "->" and that's it.  Will there be further trouble or 
discrepancy to think of Ruby reference as a pointer?
