Maybe we've gone over this before but, if so, I don't remember ...

What would [.]method() mean?

What do these do?

	if $a [<] @b { ... }		# if $a < all(*@b)		???
	if @a [<] @b { ... }	        # if $a[0] < all(*@b) && 
					#    $a[1] < all(*@b) &&
					#    $a[2] < all(*@b) &&  ...  ???

	$a [&] @b			# all($a,*@b)		???
	@a [&] @b			# all(*@a,*@b)		???

	%hash = (@a [=>] @b);		# %hash{@a} = @b;	???

I'm not even sure how to hyper these two.  I guess if I had an array
of "range objects" I could hyper ;

Would this write to several filehandles?

	print @file_handles [:] "fooey!\n";

>    ..   - range

And this is the one that made me start thinking about hypering the
others

	@a = @b[..]@c	# @a = ($b[0]..$c[0], $b[1]..$c[1], ...) ???
	@a = $b[..]@c	# @a = ($b..$c[0], $b..$c[1], ...)	???
	@a = @b[..]$c	# @a = ($b[0]..$c, $b[1]..$c, ...)	???


I know that this stuff probably seems obvious to everyone, but I'd
rather have it explicit just in case  :-)
