C+- (pronounced "C more or less")
Unlike C++, C+- is a subject oriented language. Each C+- class instance,
known as a subject, holds hidden members, known as prejudices or undeclared
preferences (which are impervious to outside messages), as well as public
members known as claims or boasts. The following C operators are
overridden as shown:
> better than
< worse than
>> much better than
<< forget it
! not on your life
== comparable, other things being equal
C+- is a strongly typed language based on stereotyping and self-righteous
logic. The Boolean variables TRUE and FALSE (known as constants in less
realistic languages) are supplemented with CREDIBLE and DUBIOUS, which are
fuzzier than Zadeh's traditional fuzzy categories. All Booleans can be
declared with the modifiers strong and weak. Weak implication is said to
"preserve deniability" and was added at the request of the D.O.D. to ensure
compatability with future versions of Ada. Well-formed falsehoods (WFFs) are
assignment-compatible with all booleans. What-if and why-not interactions
are aided by the special conditional "evenifnot X then Y".
C+- supports information hiding and, among friend classes only, rumor sharing
Borrowing from the Eiffel lexicon, non-friend classes can be killed by
arranging contracts. Note that friendships are intransitive, volatile, and
non-symmetric.
Single and multiple inheritance mechanisms are implemented with random
mutations. Disinheritance rules are covered by a complex probate protocol.
In addition to base, derived, virtual, and abstract classes, C+- supports gut
classes. In certain locales, polygamous derivations and bastard classes are
permitted. Elsewhere, loose coupling between classes is illegal, so the
marriage and divorce operators may be needed:
marriage (MParent1, FParent1);
//child classes can now be derived
sclass MySclass: public MParent1, FParent1
{ // define MySclass
sclass YourSclass: public MParent1, FParent2
// illegitimate
divorce (MParent1, FParent1);
marriage (MParent1, FParent2);
sclass YourSclass: public MParent1, FParent2
{//OK now
Operator precedence rules can be suspended with the directive #pragma dwim,
known as the "Do what I mean" pragma. ANSIfication will be firmly resisted.
C+-'s slogan is "Be Your Own Standard."
