No, because that might not be what you want your code to do. As a JavaScript programmer you have to understand what function scope means, and how to use it appropriately. If "hid" is a variable that's in scope when you define an anonymous function, your functions will refer to that specific variable. If you define multiple anonymous functions in the same scope, they will likewise all reference the same specific variable (and sometimes that's what you want). If you want each new anonymous function to have its own separate variable named "hid", then the way you tell the compiler what you want is by wrapping another function around the code that generates your anonymous function, and passing "hid" in as the argument to the wrapper function. Having the compiler try and second-guess what it thinks you *meant* would be bad, because someday some JavaScript programmer would try to share a variable between multiple anonymous functions, and would be scratching their head trying to figure out why the "smart" compiler was failing to obey the rules of JavaScript function scope.
