Can anyone tell me if there is a function in Allegro CL which finds the 
arity (= number of arguments) of a function or closure? Preferably 
also returning the number of optional arguments following the obligatory 
ones, and which arguments are keywords and must therefore be followed by 
corresponding values?

Thanks,
