Overview

Represents a literal token entity to avoid any quotation marks on inspect. Parser::AST will recursively call nodes, using ‘inspect` for anything that’s not a ‘Node` type, so we can cheat to get the macro language in here.

• #initialize(string) ⇒ LiteralToken constructor

  A new instance of LiteralToken.

• #inspect ⇒ String

  Won’t show quotes around it, which we need for literal tokens.
