I want that too.  It would be nice for the []= method where the
value is always the last argument.  Or any method where you
want optional arguments first or in the middle.

In general, this:

def foo a, b, c=x, d=y, *other, e, f
    ...
end

should be equivalent to:

def foo a, b, *remaining
    e,f = remaining.slice!(-2,2)
    c = remaining.empty? ? x : remaining.shift
    d = remaining.empty? ? y : remaining.shift
    other = remaining
    ...
end

Want to submit an RCR for this?  I've already done my fair
share.
