Don't forget about:

 my $var = do { if (predicate) { expr1 } else { expr2 } };


I know TIMTOWTDI, but this is ridiculous. It clearly shows the history
of the language (incl. it's C inheritance); not all syntax rules were
introduced at the same time. The last version looks like it's been
borrowed from LISP.

In case you'd doubt if this really works, here's some real code:

    #! perl
    for $i (0..1) {
        my $var = do { if ($i) { 'true' } else { 'false' } };
        print "i = $i, $var\n";
    }

Result:

  i = 0, false
  i = 1, true
