struct T()
{
string[] tags;
this(string[] tags...)
{
this.tags = tags; // typesafe variadic function parameter `tags` of type `string[]` cannot be marked `return`
}
}
void test()
{
T!() t;
}
The trouble here is this(), being a template, gets attributes inferred. `return` is inferred for `tags`, which later on fails because such parameters cannot be `return`.
