False positive for select_first_vs_detect when first is first(N)

[owst]

With this example code:

(1..100).select { |i| i >= 50 }.first(5)

fasterer 0.10.0 reports Array#select.first is slower than Array#detect..

However, this is only true when Enumerable#first takes no argument; here we want the first 5 matching elements and detect does not support that functionality.

I suggest that this detector only fires when first is passed no argument

hey @owst, thanks for reporting, I've released fasterer 0.10.1 with this bugfix!
