Initialize integer literal to std::size_t

Question

There are known ways to manipulate the type of an integer literal

0L;  // long
3U;  // unsigned integer
1LL; // long long

Depending on the function, you may also be able to do this and may find it cleaner:

auto result = func(1, some_var);

For example, I've done this with std::max:

auto result = std::max(0, std::min(index, vec.size()-1));

By explicitly specifying the template instantiation, the casts can be implicit. However, do note that this is a cast, so is susceptible to errors which Potatoswatter's brace initialization isn't.
