In his introduction to this most welcome republication (and second edition) of his logic text, Heil clarifies his aim in writing and revising this book: 'I believe that anyone unfamiliar with the subject who set out to learn formal logic could do so relying solely on [this] book. That, ...
First-order logic is also known asPredicate logic or First-order predicate logic. First-order logic is a powerful language that develops information about the objects in a more easy way and can also express the relationship between those objects. First-order logic (like natural language) does not...

It returns a new ZodArray instance. This means the order in which you call methods matters. For instance: z.string().optional().array(); // (string | undefined)[] z.string().array().optional(); // string[] | undefined .element Use .element to access the schema for an element of...
The awkward code for using the auto declaration syntax with a class that has a declared but deleted or inaccessible move constructor, can be rewritten in a concise and elegant way with the $no_move keyword. Conceptually it's the opposite of a std::move, requesting “don’t attempt to ...
Introduction Recent years have seen a revival of interest in extending ML's predicative type system (3), with impredicative quantification in the style of System F. Since type inference for Curry-style System F is known to be undecidable (25), many proposals have relied on various type ...
