Overview

Represents a word within a line of text. Words are the nested level of the text-based AST. They are identified by word boundaries (regex b).

Examples:

word = WordNode.new("hello", line_number: 1, word_index: 0, start_col: 0, end_col: 5)
word.content    # => "hello"
word.signature  # => [:word, "hello"]
