import std.stdio;
import std.traits;
auto createVoldemortType(int value)
{
struct TheUnnameable
{
int getValue() { return value; }
}
return TheUnnameable();
}
void main()
{
auto voldemort = createVoldemortType(123);
//f57.main.voldemort
writeln(fullyQualifiedName!voldemort);
}
fullyQualifiedName doesn't work for Voldemort types; is there a
way that we could change this? Then at least you could do:
fullyQualifiedName!voldemort ~ typeof(voldemort).stringof
