• result of appending y to xs = reverse of [ y, reverse of xs ]
• reverse of [ ] = [ ]
• reverse of [ {"ES": "Estonia", "MX": "Mexico"}, [ ] ] = [ {"ES": "Estonia", "MX": "Mexico"}, [ ] ]

• if reverse of [ ] = [ ], then [ {"ES": "Estonia", "MX": "Mexico"}, reverse of [ ] ] = [ {"ES": "Estonia", "MX": "Mexico"}, [ ] ]

• if [ {"ES": "Estonia", "MX": "Mexico"}, reverse of [ ] ] = [ {"ES": "Estonia", "MX": "Mexico"}, [ ] ], then reverse of [ {"ES": "Estonia", "MX": "Mexico"}, reverse of [ ] ] = reverse of [ {"ES": "Estonia", "MX": "Mexico"}, [ ] ]
