Can you explain this a bit better? 
By saying the slowness is due to copy-on-write semantics, 
do you mean that using the indexing operator is making a copy of
a each time I access it?

Sorry if the question sounds stupid, I do things this way sometimes in order to 
bounds checking, but if I am doing it wrong I have quite a bit of code to fix ;)
