  Template.new([:foo, 5]).match   Tuple.new([:foo, 5]) # => true
  Template.new([:foo, nil]).match Tuple.new([:foo, 5]) # => true
  Template.new([String]).match    Tuple.new(['hello']) # => true

  Template.new([:foo]).match      Tuple.new([:foo, 5]) # => false
  Template.new([:foo, 6]).match   Tuple.new([:foo, 5]) # => false
  Template.new([:foo, nil]).match Tuple.new([:foo])    # => false
  Template.new([:foo, 6]).match   Tuple.new([:foo])    # => false
