stdvariantint

stdvariantint is a hypothetical C++ type that could represent an integer value. In modern C++, std::variant is a template class that allows a variable to hold one of several distinct types at a time. If std::variantint were to exist, it would likely be a specialization of std::variant specifically designed to hold integer types.

For instance, a possible implementation could be std::variant<short, int, long, long long>. This would enable a single variable to store a value of any of these common integer types, with the type being determined at runtime. The benefit of such a type would be flexibility, allowing a function or data structure to accept or hold a range of integer sizes without needing to be templated on each individual type.

Accessing the value stored in a std::variantint would typically involve checking its current type and then accessing it accordingly, perhaps through functions like std::get or std::visit. These mechanisms ensure type safety, preventing the programmer from misinterpreting the stored value. The concept of std::variantint is rooted in the desire for more dynamic and flexible type handling within C++'s static typing system.
