some missing features

[DracoKinerek]

So, here's what we need:

• += -= *= /= %= ^=
• array functions

so the += -= etc are self explanatory, it changes x = x+1 to x += 1
and the array functions should be:

var arr = [1, 2, 3]
arr.extend(4)
print(arr) #4

Can you try https://radon-project.github.io/docs/arrays.html this implementation and give your feedback.

There are lots of predefined methods available. You can check the docs for more details.
