# 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`.
