Can I place a dynamic array, an associative array and a string to
a union and work with all elements? They are built-in types, but
actually not primitive ones (this is not allowed in C++ for
example). That's why I'm in doubt. I'm trying to implement
something close to variant type (with a few restricted underlying
types) for education purposes.
union Foo {
int[] array;
int[string] map;
string str;
}
Foo u;
u.array = [];
u.array ~= 20;
u.array ~= 31;
writeln(u.array);
u.map = (int[string]).init;
u.map["test"] = 20;
u.map["value"] = 31;
writeln(u.map);
u.str = "test";
writeln(u.str);
This code works as I expected but I'm unsure that it's correct.
