My previous comment was merely an attempt to mention how participating in this flamewar leads nowhere. I'm certainly not about to get into it by discussing details of the good and the bad and even the necessity of compile time checks of whether a string is a url. Hundreds of books have been written on the matter, and the results are still inconclusive. > Is it my opinion though? Or did I pull it straight out of Building Secure and Reliably Systems, a book written by Google engineers to express industry best practice for developing software at a scale? Yes and yes, you happen to share their opinion. Now, should we pretend that appeals to authority turn an opinion into fact now? If so, to whose authority should we appeal? Theirs? The different google engineers who work in more dynamic languages? Hell, designers of dynamic languages who have worked at Google? The people who designed and work in LISP or any of its derivates? Whose authority weighs more? Or maybe we should acknowledge that appeals to authority hold no real decisive value in deciding something like this, and instead contribute to studies trying to gauge how effective different type systems actually are. Except that even those turn into flamewars: https://www.hillelwayne.com/post/this-is-how-science-happens/ https://www.hillelwayne.com/post/this-is-how-science-happens...
