It means that they are first class citizens, there is no
difference to any other object type. They are allowed in
the same context as other objects of other types.
Example: you can write
and Python will try to print this object, regardless
whether it is an int, a string, a function, a traceback, a class,...
Notabene the entry "a function":
f is not called, since it is a first class object.
In order to call f, you need the call syntax, and Python will
try to call the object, if there is a way to do so.
VB for example would always try to call f, with or without
