Speed very much depends on what is the most likely value to occur in the tests. length for sure is not always faster.
Hm. You seem to be implying that the speed of length varies with the length of the string?
Whilst that would make sense with C; it makes no sense at all with length, which doesn't need to scan the string to find its length.
Which makes me a little suspicious of the benchmark.
Update: Of course; the affect you are seeing it due to stringification of numeric values.
