cURL was created by Daniel Stenberg, Haxe was created by Nicolas Cannasse. (EDIT: beaten)<p>My favourite Haxe feature is compile-time macros. This leads to massive meta-programming and language extension capabilities. My least favourite aspect is that it does not strictly unify or abstract every target language &amp; runtime, so you end up writing in that language&#x27;s semantics but using Haxe as syntax sugar. (Good for C++, less useful for other targets.)
