Fair enough. I said "allegedly" because I had never personally measured the performance difference.

Even though you could construe map as "half as fast" (or twice as slow) as the equivalent comprehension, I don't see a difference of ~1 usec making any difference in my code thus far. Good to know, though.

Yup, for very large calculations, or certain use cases, it can make much larger differences. It all depends on your use case.
