Given an elisp symbol foo with a symbol-function defined in C. (That
is, (symbol-function 'foo) prints #<subr foo>.) Is there any way to
find out (from elisp, of course) if foo evaluates its arguments? 
(Compare with when the function is defined in elisp. Then,
symbol-function returns a list, and if the car of the list is 'lambda,
the arguments are evaluated. If it is 'macro, we cannot be sure. Right?)
