Console function dumpFunctions? dumpClasses?

I'm trying to run two very important console functions.

I run the fps demo and hit the ~ key to bring up the console window.

Then I type dumpFunctions();
or
dumpClasses();

Console says it can not find the functions? I thought these functions were suppose to dump all of the function/class info?

Can anyone tell me how to run these functions? I feel dumb asking this one.
