This is something that was pointed out to me (by Sawyer? can't recall) a while ago as an unintended benefit. In short, if I wanted to repurpose syntax such as my Dog $spot, I'd be stepping on existing syntax. However, by creating a new syntax with an unambiguous scope and is guaranteed not to run on older versions of Perl (short of something really bizarre going on), we have a brand new syntax which is guaranteed not to clash with existing usage.

Further, because its scope is well-defined, we can play around with new syntax in that scope. Just adding a has function or a method keyword to the language could break all sorts of existing code that is already trying to do something like that. But by doing it in a new scope, we're safe.
