Agreed.

I'm not sure of the []s, remember &postcirumfix:<[ ]> creates *new*
containers:
[EMAIL PROTECTED] = $bar;
# @array[0] unchanged
Compare this to:
(@array,)[0] = $bar;
# @array[0] changed to $bar
So, I think, if we ditch Perl 5's special \(...),
\(@array,); # should be the same as
\do { (@array,) };
This has the consequence that
(\(@array,))[0] = $bar;
changes @array[0].
