An alias defines a local macro.
A typical use case is to provide access to a shadowed field.
Alias are not members of a struct and thus are not part of the model and cannot be accessed.
A = a // A is an alias to a
a: {
d: 3
}
b: {
a: {
// A provides access to the outer "a" which would
// otherwise be hidden by the inner one.
c: A.d
}
}
a: {
d: 3
}
b: {
a: {
c: 3
}
}
