I don't have any good ideas to solve that either, but I figured it was
worth mentioning.

The problem is usually in the construction phase, where it's a lot
easier to construct the list, whereas for vectors you'll likely want to
first construct a list and later convert it to a vector.

Growable vectors would be nice, but they're a different beast (need
a different low-level representation).
