The non-lazy map and filter always make a new array or dictionary, which is often consumed immediately into a Set. Using `lazy` avoids that intermediate allocation, as well as the need to loop over the array or dictionary a second time. This is a micro-optimization, but several of these accessors are accessed fairly frequently, so we might as well make them faster. |
