Provolone and assumed its current large size. The smaller sized variant is called provola and comes in plain and smoked (""affumicata"") varieties. Modern provolone is a full-fat cow's milk cheese with a smooth skin, produced mainly in the Po River Valley regions of Lombardia and Veneto. It is produced in different shapes: like a very large sausage which may be up to in diameter and long, in a truncated bottle shape, and in a large pear shape with the characteristic round knob for hanging. The typical weight is . Provolone is a semi-hard cheese with taste varying greatly from "provolone piccante"
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
