In this interpreter, each value has a mutable field "marked" which is used during the marking phase. A number in the Data column does not mean it is a NumV.

The returned function takes two lists. If both of them are not empty, it takes the first element...

You're correct in that the 'x in the named expression of the inner Let refers to the 'x that was defined in the outer Let.

Could you share some of your insight? Why should 1 be included when it can not be written as a product of 2, 3 and 5? This had me confused for quite some time as well. 1 belongs to the list because 1 actually has no prime factors at all. Or in other words, an empty product is 1. So if we take zero ...

Ich wohne in der Gegend um Aschaffenburg herum, mir wäre es also am liebsten, wenn die Kommunikation ganz übers Internet ablaufen könnte, am beste...
