[XeTeX] Dinosaurs

[Tobias Schoel]

Shouldn't real dinosaurs (real as in MTV Real Life) calculate using only 
the Peano Axioms and the unary system? I mean, the natural numbers and 
the peano axioms are nature given / god given (choose whatever you like) 
and every human before homo sapiens had only the cognitive capabilities 
to use the unary system: “Hey, I saw ||||| deer, let's go hunt them.” 
“Oh no, I saw ||| lions, they would kill us.”

Slide-Ruler? Calculator? Hole cards?
