Sometimes you have a function that receives a parameter shadowing an existing
function or variable in the parent scope.
In _some_ cases I would like to use the same variable name to avoid having to
come up with new names. Contrived example ahead:
```js
import path from "path"
function doSomething (_path) {
if (path.dirname(_path) === "/" ) {
// ...
} else {
}
}
```
It would be nice if there was a special construct like `typeof` or `instanceof`
that would take a name and evaluate to whatever
variable / function of the same name existing in the parent scope (or undefined
otherwise).
```js
import path from "path"
function doSomething (path) {
if ((insteadof path).dirname(path) === "/" ) {
// ...
} else {
}
}
```
In this case the expression above using the made-up `inteadof` operator would
evaluate to the imported `path` variable
instead of the `path` variable name.
