Just because you can, doesn’t mean you should.

Developer if forced (by himself probably) to overwrite all methods to prevent raise NotImplementedError xD

var list = new List<string>() { // Assume some items in the list };

for (var i = 0; i < list.Count; i++)
{
    var item = list[i];
    list.Remove(item);

Simple alternative to List.Clear()

The beauty is that every case is the best (also worst) case!

When scientists write code, sometimes it's not pretty. It's rather redacted ("thing" was not "thing" in the original). I especially love that the Bash part uses `` rather than $().
