For example, if there were two states of a light switch, they might be called `:on` and `:off`. In situations where the set of names is not finitely enumerable (i.e., where name conflicts might arise) it is frequently best to use symbols in some package other than `keyword` so that conflicts will be naturally avoided. For example, it is generally not wise for a program to use a keyword1 as a property indicator, since if there were ever another program that did the same thing, each would clobber the other's data.
