PERL6

pugs> my ($car, @cdr) = (1..10);
pugs> say "my other $car is a {@cdr}";
my other 1 is a 2 3 4 5 6 7 8 9 10

Putting the braces outside the data type indicator is braindead and reeks of PHP. There's a good reason shells use ${var}; it makes the interpolation simpler to understand because there's only one character that delimits interpolated values. (Or in Perl's case, three, but that's another gripe for another thread.)
