What is the word pack in C++ draft?
What is the pack means in the C++ draft standard [basic]p3? Could you provide some concrete explanation, if cannot be explained in precise term?
An entity is a value, object, reference, structured binding, function, enumerator, type, class member, bit-field, template, template specialization, namespace, or pack.

For future reference, the wp has an index. A word search there will usually bring you to the definition of things that pop up in the standard.

The standard also has an index and if we search for pack in the index we have the following entry for pack:
pack, [temp.variadic]
which leads to [temp.variadic]p4 which says:
A pack is a template parameter pack, a function parameter pack, or an init-capture pack.
The number of elements of a template parameter pack or a function parameter pack is the number of arguments provided for the parameter pack.
The number of elements of an init-capture pack is the number of elements in the pack expansion of its initializer.

do you have any advice about reading the C++ draft, or is that just I think it's hard to understand? Or could you provide an approximation about how long it will take to understand it? Thanks for your answer and reading.
