# NOTE: I initially wrote this as `EmailValidator` but it ended up clashing |
|
# with an indirect dependency of ours, `validate_email`, which, turns out, |
|
# has the same approach as we do, but with an extra check disallowing |
|
# single-label domains. Decided to not switch to `validate_email` because |
|
# we do want to allow at least `localhost`. |
