# A literal (value) is a token that represents a data value in the parsed
# language. For instance, in Ruby data values such as strings, numbers,
# regular expression,... can appear directly in the source code as text.
# These are examples of literal values. One responsibility of a tokenizer/lexer is
# to convert the text representation into a corresponding value in a
# convenient format for the interpreter/compiler.
class Literal < Token
# @return [Object] The value expressed in one of the target datatype.
attr_reader :value
# Constructor.
# @param original [String] the piece of text from input
# @param pos [Dendroid::Lexical::TokenPosition] line, column position of token
# @param symbol [Dendroid::Syntax::Terminal, String]
# @param aValue [Object] value of the token in internal representation
def initialize(original, pos, symbol, aValue)
