Subject: Simple method overhead

Hi all.

I have the method like:
class MyCoolClass
  def initialize
    @var = []
  end
  
  #some other methods push values to @var

  #here is method of interest:
  def [](idx); @var[idx] end
end

I have those, a bit confusing, profiling results:

Total   Self    Children	Calls    Name
0.09    0.05    0.04        66565    MyCoolClass#[]
0.04    0.04    0.00        66565    Array#[]

The strange thing is: method MyCoolClass#[] spends so much time inside itself, though ALL it do - only call Array#[].
Is this normal? Maybe, because of so huge calls count, but I can't understand this :(

Thanks.

V.
