*Preconditions*: T is *Cpp17DefaultInsertable* into list[.](#1.sentence-1)

[2](#2)

[#](http://github.com/Eelis/draft/tree/9adde4bc1c62ec234483e63ea3b70a59724c745a/source/containers.tex#L9315)

*Effects*: If size() < sz,
appends sz - size() default-inserted elements to the
sequence[.](#2.sentence-1)

If sz <= size(), equivalent to:list<T>::iterator it = begin();
advance(it, sz);
erase(it, end());
