=> local args; [ '+' #continue => pushItem args; #generatedString(args#back) display_literal ]* #generatedString(variable): this directive is valid only for template-based and translation scripts. The directive is put into a sequence of tokens and will be applied on the rest of the sequence: the output file is redirected into the string variable passed to the argument variable, which becomes the new output stream where code generation will be processed. If you don't care about the result, you can pass null instead of a string variable.
