Subject: Looking up properties and speed

Hi,

In Javascript, if one were to use the same property value twice or more,
one would store it in a local variable because looking up the property
slows things down.

Is the situation the same in Ruby? Is there any speed difference between
these:

def foo
  val = obj.prop
  puts val
  puts val
end

def boo
  puts obj.prop
  puts obj.prop
end

I assume not because I think the reason it's like that with Javascript
is because of the DOM (yeah, that's not strictly Javascript).

Cheers
