Well, functions return values for a reason and it's not that hard to ignore a
return value. Is it annoying? At times, yes. Worth adding some language construct
to the langauge to remedy it? Definitely not.

Here, this is what I use:

procedure ignore(object x)
    -- Do nothing, just ignore the object passed
end procedure  -- ignore

ignore( seek(fn, 100) )

It's not that hard to implement and use, looks neat and clear, and most
importantly doesn't change Euphoria in any way.
