It's absolutely possible.
I see two ways of handling this.
- Fail silently
If there is no function passed to subscribe, then we return false, and do nothing more. - Create exception
If there is no function passed to subscribe, then we throw an exception and do nothing more
While I would prefer option 2, I think that option 1 is a smaller change from current behaviour, so for the sake of easy upgrades, that should probably be the option for now.
Perhaps in v2.x we can throw exceptions when users of the library are doing silly things

Thank you for the speedy response - failing silently seems a sensible approach for v1.x.
