@mathias What do you think of having `function.argumentNames` available in `function` scope? Similar to meta properties proposed here: https://github.com/allenwb/ESideas/blob/master/ES7MetaProps.md … It's a common use-case for debugging and argument assertion.
Do you want to get the argument names of a random function or do you want access to it in the function itself? Meta properties don’t leak and can’t be used from the original function body.
Also if you add it as a property to all functions then minifiers mangling function params would be unsafe because it would change runtime semantics.
This is what I would like: ```js function foo() { // Only available inside the function console.log(foo.argumentNames); //=> ['unicorn'] } const unicorn = true; foo(unicorn); console.log(foo.argumentNames); //=> undefined ```
I want access to it inside the function itself.
