commit b7c92b414cbf3f31686a121078d99cc1143dcfd5
Author: Father Chrysostomos <[email protected]>

Postfix dereference syntax
Barely tested.
$_->$* means $$_ (and compiled down to the same op tree)
$_->@* means @$_ ( ditto ditto blah blah blah )
$_->%* means %$_ (...)
$_->&* means &$_
$_->** means *$_
$_->@[_] means @$_[_]
$_->@{_} means @$_{_}
$_->&*() means &$_(), which means $_->() (pointless)
I forgot $_->*{HASH}.
$_->@* is not always equivalent to @$_, particular in contexts like
@foo[0], which cannot be written foo->@*[0]. (Just omit the asterisk
and it works.)
