Programmatically creating functions

[Ian Eure]

So, I have a list of symbols:

'(foo bar baz)

I want to iterate over the list and create a function from each which  
does something like this:

(defun call-foo ()
  (interactive)
  (invoke-stuff 'foo)

How can I accomplish this? I can't figure out how to create the  
function. I've tried a number of approaches, but have not met with  
success.

 - eval'ing the defun. Returns a function symbol, but I can't call  
it. Maybe it's only created within the scope of the (eval) and not  
callable from outside?

 - Creating a symbol and using fset to assign a lambda to it's  
function cell. It sort of works, but I'm unclear on how to pass a  
variable function name to defun, nor am I clear on how I can make sure  
it calls invoke-stuff with the right symbol.

Help?
