Provolone Provolone Provolone () is an Italian cheese. It is an aged "pasta filata" (stretched-curd) cheese originating in Casilli near Vesuvius, where it is still produced in pear, sausage, or cone shapes varying from long. Provolone-type cheeses are also produced in other countries. The most important provolone production region today is Northwestern Italy and the city of Cremona. Provolone, provola, and provoleta are versions of the same basic cheese. Some versions of provolone are smoked. The term "provolone" (meaning "large provola") appeared around the end of the 19th century, when it started to be manufactured in the southern regions of Italy
Type system or an "effect system", which enables even more program specifications to be verified by a type checker. Beyond simple value-type pairs, a virtual "region" of code is associated with an "effect" component describing "what" is being done "with what", and enabling for example to "throw" an error report. Thus the symbolic system may be a "type and effect system", which endows it with more safety checking than type checking alone. Whether automated by the compiler or specified by a programmer, a type system makes program behavior illegal if outside the type-system rules. Advantages provided by programmer-specified type systems include: Advantages
