Semi-Groups:
 - Type with a concat method (String, Integer e.t.c by default)
    e.g. "a".concat("b")
    
Monoid:
  - Semi-group with special element that acts like a neutral identity (seen as a promotion)
    - e.g would be 0 in Sum (0.Sum(anything) is anything)
    - e.g would be "true" in All (true.All(anything) = is anything 
      - e.g. true.concat(false) === false, true.concat(true) == true)
  - Some semi-groups cannot be promoted to monoids
