That certainly makes your suggested syntax look comparatively nicer :-)
I don't know what `{}` does in Javascript, but it looks like it is a
set, or a list, or some other sequence or collection. It doesn't look
like a mapping, since a mapping requires the elements come in key+value
pairs. The syntax above doesn't look like the elements are pairs.
Rust has the same issue (thanks Brett for the link):
User {
email: email,
username: username,
active: true,
sign_in_count: 1,
}
defines a struct with fields email etc. With the field init shortcut we
get:
User {
email,
username,
active,
sign_in_count,
}
whioh again looks like a single entity `email` etc, not a pair (email
key, email value).
So I will grant you that a least your proposal looks like a pair:
param = <blank>
where the value of <blank> is implied. So better than the
Javascript/Rust syntax.
