Conceptually, they're closely related. In particular, a range behaves
a lot like an any() junction. Some differences:
1. An any() junction always

How does a Match compare to a Parcel?

When Larry decided that Perl 6 would incorporate concepts from
prototype-based objects, he did so at least in part because it's more
intuitive for people to work with, e.g., "a cow" than it is to try to
work with "the concept of a cow" as a thing unto itself. In a similar
way, I think that Perl's
First off, let me weigh in on Damian's original point: I agree that
Junction!eigenvalues should be renamed to more accurately reflect what
it is (perhaps to something like Junction!seedvalues, since what it's
really trying to produce is a list of the values that it's using to
define the Junction),

I don't see any problem there. Mason's suggestion only deals with the

This is going to be a rambling answer, as I have a number of questions
but no firm conclusions. Please bear with me.

If I'm following this correctly, shouldn't we just say that Duration
does Num? That way, a Duration can be used exactly like a Num is
(with units measured in seconds); but it could also have special
capabilities above and beyond what a Num can do, if such capabilities
are needed.

Here's my proposal for how to handle dimensionality in Perl 6:
Create a "units" trait that is designed to attach to any Numeric
object. Dimensional information gets stored as a baggy object - that
is, something that works just like a Bag, except that the count can
go negative. (I don't know if
