Sweeten your JavaScript: hygienic macros for ES5

Abstract

Lisp and Scheme have demonstrated the power of macros to enable programmers to evolve and craft languages. In languages with more complex syntax, macros have had less success. In part, this has been due to the difficulty in building expressive hygienic macro systems for such languages. JavaScript in particular presents unique challenges for macro systems due to ambiguities in the lexing stage that force the JavaScript lexer and parser to be intertwined.
