Hi,
I'm trying to do something similar to what Kotlin allows with
assigning to member variables from a map. The syntax is very
readable and looks like:
class User(val map: Map<String, Any?>) {
val name: String by map
val age: Int by map
}
So I'm trying to do something similar in D:
mixin template MapMembers(alias aa) {
foreach (name; typeof(this).tupleof) {
// if name is in aa, then mixin(m = aa[" ~ m ~ "]) ... ish
}
}
struct User {
this(Variant[string] aa) {
mixin MapMembers!aa;
}
}
Seems I can't do typeof(this) inside the mixin.
One workaround is to explicitly pass the type "User" to the
template mixin, but it feels like this is something that should
work and I'm just unfamiliar with template mixins and their usage.
Cheers,
- Ali
