In python even a class can be decorated. Also features of instances
can be added at run time from programs by different programmers
or even programs from machines by the code generation scheme
used in many CAD tools.

Nowadays the concept of a structure is not clear without
specifying the language used in programming.

A list is a structure of non-homogeneous types of items  in LISP,
PERL and PYTHON.

But the cases are different in C++, PASCAL, ADDA, JAVA ....
