Subject: method to speed up add_data
Hello Shlomi, It is possible to speed up Statistics::Descriptive::Full::add_data by using functions available in List::Util and List::MoreUtils. Some of the other S::D subs could benefit from these as well. The speed ups I get are typically around 10-20% (range 0-45), depending largely on the size of the data. I benchmarked with 100, 1000 and 10000 records. One issue is that this approach requires the addition of two new dependencies, albeit one of them is in the core. Whether that is an issue obviously depends on how stand-alone you want the package to be. If you're open to the idea then I'll submit a patch. Regards, Shawn.
