Reply to comment by flabberghaster in ruby lets you put an array inside itself by musou

What you're actually doing in Python when you put a list into itself is to put a reference to the list into itself.

L = []
L.append(L)
L[0] is L # True

Python and Ruby arrays are heterogenous, unlike in C++, where strong typing forces us to define a common type for objects contained in the same collection. There's no way to do this with the STL <vector>, but you could do this with an object system, for example Qt, where all "Q" objects derive from QObject:

QVector<QObject*> objectVector;
objectVector.append(&objectVector);
