You use it all the time in code, and in D it's even more useful than in Python because in D a small linear scan can be very fast. To do that in my dlibs I use the function isIn(item, items), where items can be an AA too of course.

I somewhat agree. For small arrays I find it very useful, I use it all 
the time.

compare:

if (x in [1, 2, 3]) { }

if (x == 1 || x == 2 || x == 3) { }


I find the first one prettier. :)
