Jordan Rose 11cf13a255 Avoid intermediate copies when using dictionary keys as collections
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.
