what is a proto file?

[michaelpg, 2015/11/21 23:03:50]

renamed to interface.

[Dan Beam, 2015/11/23 18:56:09]

you should probably keep the file name and class name the same

+/** @interface */
+function SettingsPrivate() {}
+
+SettingsPrivate.prototype = {

nit: remove \n

[michaelpg, 2015/11/21 23:03:50]

Done.

this is weird, why is closure OK with a named function that doesn't match the
@params (assertNotReached in this patch), and a function expression matching the
@params (last patch), but warns on a function expression with the wrong number
of params (function(){})?

[Dan Beam, 2015/11/20 01:58:17]

because we have magic to identify "assertNotReached", maybe?
