Paste table data from copying from excel/libreoffice, and change <br /> to newlines
/* Quick and dirty experiment:
* Copy cells from a spreadsheet document (excel, libreoffice), and paste in a web page.
* Replace the <br /> in the cells with new lines, so when getting the innerHTML or the textContent,
* the result is "formatted".
document.addEventListener("paste", evt => {
const content = evt.clipboardData.getData("text/html");
console.log("content:", content);
const parser = new DOMParser();
const doc = parser.parseFromString(content, "text/html");

syntax gripes with Elm
There's two ways to create a record in Elm: with the "type constructor" and with the "record syntax".
The fact that there's two ways to do the same thing is already a bit disconcerting, but the worst
part is that there's no way to do it and have the best of both worlds regarding naming (which is
great for clarity, maintenance and refactoring: think about grepping on names for example).
type alias Person = {
firstName: String,
