PHP has no namespace, inherits many C-functions and is quite popular.<p>It&#x27;s easier to recall a function name than recall the namespace and the function name, isn&#x27;t it? With modern IDEs this is a none issue anyway. Though from my experience with Mathematica 5-7, the language feels a bit weird. Nevertheless it&#x27;s quite an achivement that WolframAlpha (the AI search engine) runs on Mathematica code.
