Great thinking over at Khanlou.com about types that implement
isEmpty and the weird tri-state they can be in if
Optional. I also have a self-imposed rule forbidding optional
I should probably extend this practice to
Strings, but treating
"" different from
" " gives me the heeby jeebies. So I have a
maybeBlank()->String? extension on
String that returns the string or
nil if it's empty or whitespace.
This article really calls out how insane that is.
