Does Ruby have a special stack for returning a value?

return-value

The following Ruby code

def a(b,c) b+c end

is the same as follows with Python

def a(b,c): return b+c

It looks like that ruby has the special stack that stores the final evaluation result and returns the value when a function is called.

If so, what's the name of the stack, and how can I get that stack?
If not, how does the Ruby code work without returning something?
