Hi everyone, I've been working on implementing operator overloading and would like to submit a proposal.
I think operator overloading would be a useful addition to the language. In particular I think it would be useful for defining operations on common mathematical object types such as complex numbers, vectors, matrices, and sets. I've create a working prototype that consists of: - babel plugin that rewrites operators as function calls - a polyfill which defines these functions and which call the correct argument-specific function based on the arguments' prototypes - Function.defineOperator which can be used to define which function an operator should use for the specified types - "use overloading" directive which allows users to opt-in More details can be found at https://github.com/kevinbarabash/operator-overloading. The babel plugin can be found at https://github.com/kevinbarabash/babel-plugin-operator-overloading. I also have a demo project at https://github.com/kevinbarabash/operator-overloading-demo. The design was inspired by some of the slides from http://www.slideshare.net/BrendanEich/js-resp. – Kevin
