Step 3 . In Common Lisp, symbols have multiple attributes. They can be bound to a value. They can be bound to a global function. Both at the same time.
Symbols belong to a particular package.
An earlier lab introduced the function describe. When given a symbol, describe will display these and all the other attributes. One of the attributes not previously mentioned is the symbol's property list. So if there were two people that your program needed to keep track of. They could be represented as symbols.
