The closest I can get is @(S.init.c(9).f(42)) with use of

All I can get is that the

Error: function expected before (), not S(0, 0).c of type int
- and if I prefix it with '_' it ruins toString. -> Error: no
property toString for type onlineapp.S
import std.stdio, std.range, std.algorithm, std.traits, std.meta,
std.conv, std.string, std.uni, std.meta, std.functional,
std.exception;
struct S{
int a, b;
auto opDispatch(string name, T)(T value)
if(name.startsWith("_"))
{
mixin(name[1..$], "= value;");
return this;
}
}
void main(){
S.init._a(5).writeln;
}
Now I'm more confused, as the compiler completely ignores the
if(name.startsWith("_")) constraint o.O
