This PR adds support to underscores in numeric literals, following the footsteps of [Python 3](https://www.python.org/dev/peps/pep-0515/#implementation) and [JS](https://github.com/tc39/proposal-numeric-separator). ``` 100 # 100 1_0_0 # 100 10_0 # 100 _100 # ERROR: identifier not found: _ ``` The main differences with other implementations are: * you can use as many consecutive `_` as you'd like (`10_000_000___00` is ok) * underscores *can* be found at the end of a number (`100`, `1_0_0` and `100_` are all the same)
