I vote for removing elder version of Ev completely and newer should be named
'Ev' to exactly match with perlTk's one. My opinion people will be less
confused it this case.
And to deal with it like following:
  $mw->bind('<Motion>', [$sub, Tcl::Ev(XY'), '<Motion>']);

In case you want to catch elder usage and warn users, it is better to warn
them when you'll detect elder 
  $int->call(\\"XY", sub{...}) 
construct.
