you mean : a feature of some scripting languages ?-)
Try doing this in Lisp or Python...

Er... Try writing some 'general' function (like qsort() in ansi C) 
without some 'generic' datatype. Why do you think C has void* and Java 
the Object base type ?

The use of C 's void * or java Object type is not that safe, and any 
cast error in C may have unpredictable result, while silently compiling.

So, as long as we go for your first arguments, I still think you're too 
confident in the compiler and not enough in the programmer !-)
