Thing is, this puts the loop and the code inside the loop in different places
making the code harder to read. Imagine how eu code would be if the for loop
was implemented the same way, as a function or procedure! Spaghetti-code.

With the same logic, why should the find() function exist? It only iterates
the top level of a sequence, yet it's very useful and your code can get much
faster if you structure your sequences so you can use it.
