   In case the compiler encounters a fully applied builtin (i.e.
   no currying is occurring) and the `builtins` global is unshadowed,
   it could compile the equivalent operator bytecode instead: For
-  example, `builtins.add 20 22` would be compiled as `20 + 22`.
+  example, `builtins.sub 20 22` would be compiled as `20 - 22`.
   This would ensure that equivalent `builtins` can also benefit
   from special optimisations we may implement for certain operators
   (in the absence of currying). E.g. we could optimise access
