unquote('"$moz-"#{$experimental-support-for-mozilla} "$webkit-"#{$experimental-support-for-webkit} "$opera-"#{$experimental-support-for-opera} "$microsoft-"#{$experimental-support-for-microsoft} "$khtml-"#{$experimental-support-for-khtml}')
You can use the sass-convert command to automatically fix most cases.
