Problem with return value

[Amir Ebrahimifard]

Hi
In this code :
-------------------------------

def test_method(name)
puts name
3+5
end


return_value = test_method("James")
puts return_value

return_value = test_method("James")
puts return_value

Because in Ruby, the last statement executed in a block is the block's
value. That goes for your test_method's return value, and any other
type of block you use.

Actually, 3+5 is the last statement in your test_method. Are you
surprised that the value is 8?
