vctrs: a type system for the tidyverse
...is little more complex:
<https://github.com/r-lib/vctrs/blob/master/R/c.R>)
On top of this foundation, vctrs expands in a few different ways:
- To consider the ?type? of a data frame, and what the common type of
two data frames should be. This leads to a natural implementation of
`vec_rbind()` which includes all columns that appear in any input.
- To create a new ?list\_of? type, a list where every element is of
fixed type (enforced by `[<-`, `[[<-`, and `$<-`)
- To think a little about the ?shape? of a vector, and to consider
recycling as part of the type syste...

I must admit I'm a bit surprised here. rbind is one of the few places that
immediately come to mind where R takes a fail early and loud approach to
likely errors (as opposed to the more permissive do soemthing that could
