Hmm, well, with the currently defined adverbs you'd have to say
qx:s(0)'echo $VAR'
but that doesn't give you protection from other kinds of interpolation.
I think we need two more adverbs that add the special features of qx and qw,
so that you could write that:
q:x/echo $VAR/
where ordinary qx/$cmd/ is short for
qq:x/$cmd/
Likewise a qw/a b/ is short for
q:w/a b/

: to have something done in some_other_way, you just should insert
: :some_other_way adverb, and that is! perl will DWIM happily :)
Well, that's perhaps a bit underspecified from the computer's point of view.

It would get very confusing visually, even if the computer could sort it out:
@a >= @b
@a >=< @b
But there are some things that would be completely ambiguous:
%hash<foo><bar>
%hash<foo><baz()
: or maybe even we could see consistant to go after +<< +>> and alike, and
: make old < and > written as +< and +> (and then lt and gt suddenly could

I think people would rise up and slay us if we did that. We're already
getting sufficiently risen up and slain over Perl 6.

Well, yes, but sometimes the weights change over time, so it doesn't
hurt (much) to reevaluate occasionally. But in this case, I think I
still prefer to attach the "exotic" characters to the exotic behaviors,
and leave the angles with their customary uses.
