You're right - if I use a Set then the lookup is astonishingly fast by 
comparison.
Is it OK to combine arrays and sets, though? For example, I have a Set 
of things I need to grep and an array I don't, and these need to be 
combined as an array. So, is:

final = set + array

...OK, or do I need to do

final = set.to_a + array

...or even something else?
Thanks.
