It's not just an alias for 'runas'. It seems to be able to configurably block user input for sudo'd commands, retain the existing environment, ditch it and open a new window, and remember that you've sudo'd in the last minute or so.

@OmnipotentEntity@Pilgrim it's actually not just a wrapper for runas. There's a lot of other plumbing here to get the console handle you're actually using plumbed to the target application. That's the magic that lets you actually interact with the elevated process in the same terminal.
With runas, the target application is just stuck in a separate console window (gross)
