        #  specific contained keys or contained key, value pairings.
        # 
        # Property Maps:
        # - Starts with either `[` or `{`
        # - Key separated by `:` or `=`
        # - Deliminated by `,`
        # 
        # Property Lists:
        # - Starts with `[`
        # - Deliminated by `,`
        # 
        # For simplicity, these patterns match a generic, nestable structure
        #  which follow a key, value pattern. For normal lists, there's only keys.
        # This allow some "illegal" structures, but we'll accept those for
        #  sake of simplicity
        # 
        # Examples:
        # - `[facing=up, powered=true]` (blockstate)
        # - `[name="hello world", nbt={key: 1b}]` (selector + nbt)
