Sort of interesting at first glance.  But not obviously
different from ....  (YAL)

About return values from functions: One way to
think about it might be to use ans.  Currently, the
value of ans is local to the function, so

function f(x,y)
x+y
end
produces :
f(1,2)
ans
(void)

If ans were not local, the specific behavior asked for
would (nearly) happen.

In any case, I have thought now and then of proposing that "ans"
be made into a stack.  This idea is somewhat relevant to this
discussion, so I am just mentioning it now.  It might be nice
is this feature could be part of a more general capability rather
than a special case.

By the way, Julia proudly says that you can define functions at the
command line unlike Matlab.  They do not mention that this is just
like Octave...
