 This returns a boolean, but since constructors are very rarely
 not inlined, this always returns true for now.
 
+=item B<can_be_inlined>
+
+This method always returns true in this class. It exists so that
+subclasses (like in Moose) can override and do some sort of checking
+to determine whether or not inlining the constructor is safe.

 This creates the code reference for the constructor itself.
