But that is not correct.  The order for ln is the same as for cp and
mv in that the target getting created is the right side argument.

(Unless the -t or -T option is used to do it differently by explicit
syntax request.  Unless no target is specified in which case dot is
assumed.  I admit those two "unless" cases complicate the original
simplicity.  But the normal case is to create the right side argument
as the target of the command.)

The target getting created is the right side argument.  If that is not
clear from the documentation then improving the documentation is
always good.

Let me say with some confidence that if the order were changed to
create the left argument that people would be very upset that cp and
mv created the right side argument but ln created a left side
argument!
