I tried Python sets for the first time. They seemed workable but rather 
clunky to set up. But here is one problem on my CPython:

    x = set(range(10_000_000))

This used up 460MB of RAM (the original 100M I tried exhausted the memory).

The advantage of Pascal-style sets is that that same set will occupy 
only 1.25MB, as it is a bit-map.

While sets will not usually be that big, there might be lots of small 
sets and they all add up.

(It won't any more, as there is no C version. I've had it with that 
language.)
