Confused with chef syntax

Look at the following line of chef code:

node.default['apache']['dir']          = '/etc/apache2'

In the official chef docs, it says 'node' is an object, and 'default' is a method of it, so how can square brackets(I thought this is hash syntax) follow a method?

I come from Python background and I'm new to Ruby, maybe this is general syntax, or maybe this is Chef-specific syntax, I'm just confused about this syntax.

node.default() (which is really an alias for node.attributes().default()) returns an instance of a Chef::Node::VividMash which works kind of like a normal Hash object but implements the deep-set behavior you see there (where you can set a deeply nested key without creating the intervening levels).

tl;dr don't worry about, we do a lot of object trickery to make the DSL look as nice as possible.
