Not true, at least not in the Perl I know. :-) Here's a description of
what these do in Perl just to clarify:
$a[0][1][2]; # get a single multidimensional element
$a[0,1,2]; # get elements 0, 1, and 2 of @a
This lets you say:
($user, $home, $shell) = (getpwnam('nwiger'))[0,7,8];
Pretty cool, eh? This has been in Perl forever.
