Yes we do. I would prefer writing $foo ~ $bar rather than "${foo} ${bar}" and I am sure therere are others that would too. (Actually I would rather write $foo . $bar but that isn't going to happen.) Technically speaking, we don't "need" many things. To me, the flexibility is one of the things that makes perl, Perl. Sometimes I cat, sometimes I interpolate.

I haven't kept up on perl6 development lately, but isn't there going to be a unary version ( ~@array ) as well? or has this changed?
