text: Title: Add $RANDOM
  Body: Hello! I have an idea!
  
  Under bash, zsh, and probably others, if you type "echo $RANDOM" you get a random number. It is a different random number each time it is echoed.
  
  I thought this should be a thing in Xonsh because this post from It's FOSS on Mastodon treats it as a given that "echo $RANDOM" on the (unnamed) CLI will have this effect, but this is not the case for Xonsh.
