Oh right. I was thinking that C<any> and friends were operations, not types.
Oops.
YAML type-URIs are made up of a type-family with an optional format:
!domain.com/type#format
and:
!int
is shorthand for:
!yaml.org/int#dec
So I'm wondering if any|all|one|none can be formats of !super? And if so,
should there be a default format?

Here are some options:
---
# !yaml.org/any
letters: !any [a, b, c]
# !yaml.org/super#all
digits: !super#all
- 0
- 1
- 2
# !perl.yaml.org/one (Perl specific types)
names: !perl/one [Brian, Ingy, Mr
Inline] # (Yes, this dwims :)
# !perl.yaml.org/super-none (longer type name, no format)
sane: !perl/super-none
- Larry
- Damian
- Brian
...
It might be more forward thinking to allow any|all|one|none into the
yaml.org type repository.
!perl/glob is staying right where it is, thank you ;)
Cheers, Brian
