Strange as hypb:functionp is marked to be autoloaded and should be in hyperbole-autoloads.el. Check if it is or not. Load it manually and then test:
{M-x load-lib RET hypb RET}
Thanks for looking at it!
Got an error with that code, though -- here's what I did:
1. Loaded Emacs. Hyperbole auto-loaded.
2. Invoked the "Notes" global button -- just to make sure Hyperbole was
running and good to go.
3. Evaluated provided code
4. Invoked "Notes" global button again and this is what the debugger
gave me:
Debugger entered--Lisp error: (void-function hypb:functionp)
