- is just a quote in perl6
- can be used to "tack" things onto perl6
Used as a brace pair or quote pair
` has no special meaning and is just a quoting character
` is more or less reserved for use by user's private code through overloading/grammar warping
Old, deprecated, or other language uses
` was used to "shell out" in perl5, very tackily. Perl6 does away with that practice.
