Ok, got me :)
The example was not the best and would have better been something along
perl -e 'print "1 + 3 = ${\(1+3)}\n"'
BTW, can you think of a clunkier way to get the name of the current script as
print "Call me $${\localtime} darling.\n"
(and with some luck, that even fails :)?

But
${\foo}
(as in your example) is still shorter than
@{[foo]}
(agreed however that the latter looks nicer).
