#pragma once
// Provides for syntax sugar easing hardcoding.
// 1. concept names
// use declrefs(apple, is, fruit, water, has)
// to quickly define the named ref variables,
// referring always to the same named concept.
// the ref constructor provides for using
// 'true' and 'false' as refs.
// 2. links
// links may be quickly made with
// apple[is = fruit, has = water]
// which links 'apple' by 'is' to 'fruit'
// and by 'has' to 'water' in one line
// 3. hyphenation
// refs may be hyphenated (subtracted) to
// produce a new ref with the conglomerate name
// apple-has-water.name(): "apple-has-water"
// this may be expanded upon.
// 4. anonymous concept creation
// an unnamed instance of a concept may be created with the a() or an() equivalent functions:
// ref anongreenapple = an(apple)[color = green];
// it will be given a name such as apple-3
// 5. quick group checking
// the obverse of the a()/an() functions is provided
// by ref::isa() and ref::isan() which quickly check
// if there is an "is" link to the passed ref.
