Knowing a chain of similar operators end is rarely if ever a concern.
Having to maintain yet another mental a mental note (e.g. that an array
deref will eventually be performed) while reading a long chain of
expressions is.
This features allows code to be placed where it's performed instead of far
in advance.
@{${$h{a}[0]}
vs
$h{a}[0]->@*
(btw, can that arrow be omitted?)
