Review comment:
The docs say that "The pattern must match starting at the beginning of
`expr`" but it looks like the regex pattern you are passing in is asking that
it start at the beginning of the string via `^` in the pattern string. Can I
use a `$` in my regex to ask that it matches the end of the expr?
