As is usually, my advice is that unless you know what the performance 
hit will be in advance, implement, test and if the performance is 
unacceptable, profile and only when you know exactly what the cause is, 
optimize.  Quite often the obvious performance bottleneck, isn't. 
Similarly, though the expected bottleneck shows up just where expected, 
the performance hit is much milder then expected and performance is 

I don't mean to suggest that you don't even think about performance at 
this point, just that we concentrate on functionality. If you can show 
by past experience that implementing in a certain way will slow things 
to a crawl, then by all means, show us and suggest a way around them.
