 All of the following functions would be inlined.
 
-    sub PI ()          { 3.14159 }
+    sub pi ()          { 3.14159 }             # Not exact, but close.
+    sub PI ()          { 4 * atan2 1, 1 }      # As good as it gets,
+                                               # and it's inlined, too!
