Problem: Indigo code often contains the `$` Haskell operator,
however since the language is meant to be used by people not
familiar with Haskell it would be great to not make it a necessity.

Solution: Reduce usage of `$` in 2 places:

1. right before `do` is used for a block code
- Solved by using `BlockArguments`

2. right after `new`
- Solved by treating `new$` as one keyword
