Subject: Re: Symbol.defined?

I see that some of the core team appear to hang out here, so I thought I 
would bring it up here.

Certainly, if I were to optimize things, I would assume that the list of 
symbols is append only.  Then I would put strings of the symbols in a 
set and add in the new ones as found for each call.  After the first 
call, this would likely be pretty cheap, but there must be similar 
functionality already in place at the 'C' level, so this is really a 
request to exposed that as part of the class.  (And avoid doubling the 
amount of memory used by symbols!)
