You may find yourself frequently using «print» to simply print a variable, without alteration. «print» has a convenient shorthand form for this single case: you simply omit the word “print”, leaving just the variable within the angle brackets.

Your superior officer approaches. "<<$name>>, you've done a fine job. No, a superlative job. <<$species>> like you have no place on this cruel Earth, that rewards only greed and selfishness."
Note: you can only perform this shorthand form using variables! You cannot, for instance, write «visited()».
