[wp-hackers] Is there a way to get the callback function name out of a shortcode _programmatically_?

[Haluk Karamete]

Nikola, i'm just curious. I'm not sure as to why I should worry about the
"is_callable" matter? Why would an existing shortcode tag work with a not
callable function... see what I mean?
