As an addendum to what I said before ...
The general kind of thing I am proposing for Perl 6 to have is a
declarative syntax for more kinds of tasks, where you can simply
specify *what* you want to happen, and you don't have to tell Perl
how to perform that task.
An example of declaratives that is already specified is
hyper-operators; you don't have to tell Perl how to iterate through
various lists or divide up tasks.
I would want the set operations for tuples to be like that, but the
example code that Luke and I expressed already, with maps and greps
etc, seems to smack too much of telling Perl how to do the job.
I don't want to have to use maps or greps or whatever, to express the
various relational operations.
