The biggest concern with JSON seems to be the lack of comments. So what voodoo is Sublime Text 2 performing? Why can't we just use that?

  {
    // Sets the colors used within the text area
    "color_scheme": "Packages/Color Scheme - Default/Monokai.tmTheme",

    // Note that the font_face and font_size are overriden in the platform
    // specific settings file, for example, "Preferences (Linux).sublime-settings".
    // Because of this, setting them here will have no effect: you must set them
    // in your User File Preferences.
    "font_face": "",
    "font_size": 12,

    // Valid options are "no_bold", "no_italic", "no_antialias", "gray_antialias",
    // "subpixel_antialias", "no_round" (OS X only) and "directwrite" (Windows only)
    "font_options": [],

    // Characters that are considered to separate words
    "word_separators": "./\\()\"'-:,.;<>~!@#$%^&*|+=[]{}`~?",

    // Set to false to prevent line numbers being drawn in the gutter
    "line_numbers": true
  }
