If you forget the ;, the compiler "think" your block send something, so the
error.

You can also use foreach :

- min args:ARRAY[NUMERIC] :NUMERIC <-
  (
   + least:NUMERIC;
   least := UINTEGER_64.maximum;

   args.foreach <http://args.lower.to/> { el : UINTEGER_64;
     ( args.item i < least ).if { least := el; }
   };

   least
);

We have also to add min and max function in collections...
