Lists, floats, etc are *data*. There is plenty of opportunity for creating
data structures that contain whatever you want, organized in any fashion.
Functions are (typically) not data. Applying these attributes is a way to
define program semantics, not record data.
There are two entirely separate worlds here. Adding attributes makes great
sense, as a way to enhance the definition of your program's semantics and
operation.
