it says that Sather forces the use of return values, i.e. something
like the following needs to exist:
blah := some_method() + 4;
Yet, down the page a bit, the "divide" function is declared, and
simply "called" to load up the "div" and "rem" variables.
divide(a,b,out div, out rem);
So, am I to understand that an *out* argument in a function, is a
way to get around *having* to use use an explicit "return"
value/statement? Any benefit to doing this way, rather than
following the Sather "return a value and use it" discipline?
