And you need to do this why?

+1. Jon was using it to "compile" something then jump to it in C, by casting an array as a function, then calling it.
+2. I use it frequently to do things like have a lookup table of name to function. For example in ircu, theres a functino called "parse" which takes a line from a user, splits it up into a function and it's arguments, then scans through a table of functions and their names, when it finds one that matches that command, it calls the function with the arguments it parsed earlier. Nice 'n zippy.
