Prompted by Darren Duncan's proposal on Relation type objects
I looked at http://dev.perl.org/perl6/doc/design/syn/S06.html
and wondered how Interval type objects would fit in.
I couldn't imagine how. Now that isn't a surprise
(not for lack of imagination but for lack of perl6 knowledge).
I tried to find anything relevant but didn't succeed.
Could somebody provide some clues, please?
Can we first clarify that this describes what you are referring to:
http://en.wikipedia.org/wiki/Interval_(mathematics)
From what I've read there, I don't see an existing equivalent Perl 6 type.
Some people may confuse it with a Range, but I don't think so since a
Range progresses in discrete increments, while an Interval would be
continuous.
Moreover, the existing Set wouldn't overlap it because Set deals with
a finite collection of discrete members. (Similarly, a Relation is
explicitly discrete and finite by definition.)
I assume you aren't referring to the temporal specific thing called
an interval.
