I did a Google search of "perl equivalent of python str function", but looking in that page (first hit), there is no mention of Perl. I checked the source too, CtrlU, thinking that maybe it was hidden somewhere, but no luck.

If you look at the current google cache for that page, you'll see that it does contain the word 'perl'. Multiple times even. So that means that this page must have been changed recently, and the google bot hasn't passed by again. Wait a couple of days, and that result wont show up any more for that search query!
