Slang::Predicate - Predicates in perl6
use Slang::Predicate;
my (\α, \β) = (T, F);
say ((α → β) ∧ α) → β;
Slang::Predicate adds operators common to predicate logic directly to perl6.
Exported terms and operators are:
| Terms | Term | Example |
| True | T | T ~~ True |
| False | F | F ~~ False |
| Infix | operator | Example |
| True | T | T ~~ True |
| False | F | F ~~ False |
| Disjunction | ∨ | T ∨ F ~~ True |
| Conjunction | ∧ | T ∧ F ~~ False |
| Exclusive disjunction | ⊻ or ⊕ | T ⊻ F ~~ True |
| Conditional | → or ⇒ or ⊃ | T → F ~~ False |
| Biconditional | ↔ or ⇔ or ≡ | T ↔ F ~~ False |
| Prefix | operator | Example |
| Negation | ¬ | ¬T ~~ False |
| Verum | ⊤ | ⊤F ~~ True |
| Falsum | ⊥ | ⊥T ~~ False |
