The manual says the function name should be a string, and indicates the
brackets aren't required.
Ie
if (function_exists('editForm')) { editForm(); }

I imagine this should cause a problem, as it will try to call the function
in the evaluation, and if it isn't defined flip out. If the function
returns a boolean then the matter is further complicated.
