change `$_` to `_` #1

$_ seems like an odd choice. In the official REPL (and in node's), the result of the last evaluation is stored as _.

I chose $ as to not override the popular jQuery's $ nor Underscore.js's . On May 12, 2012 8:26 PM, "Michael Ficarra" < reply@reply.github.com> wrote:

_ is really the proper choice here. I think it's what everyone would expect. We haven't gotten a single complaint for this behaviour in the official REPL:

$ coffee
coffee> _ = require 'underscore'
{ [Function]
  _: [Circular],
  VERSION: '1.3.3',
  /* ... [snip] ... */
  template: [Function],
  chain: [Function] }
coffee> 0
0
coffee> _
0
coffee>

I agree that _ is what is expected, but Underscore.js came first and I'm not quite ready to break compatibility with the library to save a character. In the future, I'll likely allow the user to change the variable in a setting, once there are Settings.

In the meantime, you are welcome to change it on your own local copy or fork. It is literally a one character change here.

EDIT: With the recent rewrite, make that here.
