Re: [Chicken-users] apply - call of non-procedure

[Will M Farr]

Try (apply car (list (list 1 2 3))).  (apply 'car (list (list 1 2  
3))) tries to apply the symbol car, which is indeed not a function.   
Unlike common lisp, where the call would be (apply #'car (list (list  
1 2 3))), scheme makes no distinction between the symbol-value and  
the symbol-function, so operators like #' to extract the symbol- 
function are not needed.  (If you want to know more about this, the  
technical term for scheme is a lisp-1; common lisp is a lisp-2---a  
search on google should quickly turn up *lots* of discussion of these  
facts.)
