dictionary that discards old items

[Will McGugan]

Hi folks,

I need a collection class that behaves like a dictionary but when it 
reaches 'n' items it discards the oldest item so that the length never 
goes above 'n'. (Its for caching search results)

I have a vague memory of a module that does this, but I cant remember 
where I read about it. Can anyone enlighten me?


Regards,

Will McGugan
