I don't think so: we can have both.  In fact I like the idea of this built
in alias very much.  Currently I can't see any obstacles.  In the meantime
we can do

module Kernel
private
  def Criterion(&b)
    class << b; alias :=== :call end; b
  end
end

Alternatively we could suggest to put this method definition into the
standard lib.

Kind regards
