Maybe we should extract this part to mixins since we have meen using it twice.

You never set the value of @base_indent. Maybe you intended a getter for @indent.

That's wrong indeed. base indent is current indent. Maybe we should also kill the setter. It doesn't make sense.

Despite being longer, I would much rather go with default_indent. We can live with indent if you find it too long.
Makes for a simpler, more declarative API.
It's still there since project initialization.
They're _"aliases"_ to `group`.

Which makes chaining calls possible => better looking programs
This is in preparation for the next commit which introduces the `space` method to actually print a space. Besides, it's technically a space generator.
It adds breakables next to delimiters, and gives more control to the caller. Will be useful in the next commits when we add more vocab.
