Yup, and similar things will happen with grep EXPR, LIST vs grep BLOCK LIST (as well as the corresponding maps). If you're really looking to eke out those last few cycles and can do without a full block (maybe you can get by with wrapping the grep or map in a block and reusing a lexical scoped to that in the EXPR) this can shave a bit off.
