I assume you mean a "colon", like this `:'

Those :foo thingies have another nice property: they are self-evaluating,
like numbers. If you try, e.g. to eval foo, the evaluator tries to find
a variable named foo and the result is then that variable's value.

If you evaluate 'foo, the result is the symbol foo.

If you evaluate :foo, the result is :foo, like when you evaluate 1234,
where the result is simply 1234.
