Subject: Re: convert string into a variable object

Hi,

I would think it depends entirely on the use case.

You're going to need to hit 8MB memory usage before ruby is going to 
sweep and collect those string objects.

Every time you access a value in your hash by key, that is a new string 
object. It could be more efficient to use symbols to stay *under* a 
threshold, rather then go over it by creating new string objects every 
time you want to access a value in your hash.

Thanks,
Rob
