Currently, calling `this()`

returns an error as this is not declared. That means that this feature will not conflict with any JS use of `this`

. This will allow to call itself in a function or an arrow function. Examples:

```
// Factorial Function:
function factorial(n) {
return (n == 0) ? 1 : (this(n-1) * n)
}
// Factorial Lambda:
n => (n == 0) ? 1 : (this(n-1) * n)
// Fibonacci Lambda:
n => (n < 2) ? 1 : (this(n-1) * this(n-2))
// Is number a prime? Lambda:
n => {
for (let i = 2; i < Math.sqrt(n); i++)
if (n%i == 0) return false
return true
}
// Quick for loop from zero to hundred:
((n) => {
if (n > 0) this(n-1)
// Run code here that should be repeated 101 times, with n = 0 .. 100
})(100)
```

The use of a quick way to call the function you're in allows for so many expressive ways to write problems. Hoping this to be reviewed!
