> You realise an isomorphism is actually a well-defined mathematical concept, right? I think a prime example of how words loose their precise mathematical meaning is the word "function". It has a precise definition in maths but we programmers use it often with a different meaning. We used to have the terms "subroutine" and "procedure" for what we use "function" for nowadays. We even came up with the term "pure function" to refer to the original mathematical meaning of "function".
