Thanks Stefano, I got the idea!  Especially when you explain the line 6,
it's clearer to me now.  So whatever for loop did before line 6, all of
those are stored in memory, then when you called line 6, it will return
only the value part that got added to the hash a moment ago at one go
right?  I hope that is what you mean.
