 /**
  * Given a string containing a GraphQL value (ex. `[42]`), parse the AST for

  * Throws GraphQLError if a syntax error is encountered.
  *
  * This is useful within tools that operate upon GraphQL Values directly and
  * in isolation of complete GraphQL documents.
  *
  * Consider providing the results to the utility function: valueFromAST().
