Warming up --------------------------------------
               block     2.657M i/100ms
              lambda     2.589M i/100ms
                proc     2.561M i/100ms
Calculating -------------------------------------
               block     26.686M (± 3.5%) i/s -    135.499M in   5.083903s
              lambda     26.151M (± 3.9%) i/s -    132.021M in   5.056495s
                proc     25.334M (± 3.9%) i/s -    128.059M in   5.062711s

Comparison:
               block: 26686459.3 i/s
              lambda: 26150966.6 i/s - same-ish: difference falls within error
                proc: 25334065.2 i/s - same-ish: difference falls within error

Basically the same performance.
