In the following example, it seems like the signatures of fun1
and fun2 should
be equivalent. Both accept a Vector!(T, 2), the only difference
is that fun2
goes through an alias.
struct Vector(T, int N) { }
alias Vector2(T) = Vector!(T, 2);
void fun1(T)(Vector!(T, 2) vec) { }
void fun2(T)(Vector2!T vec) { }
unittest {
fun1(Vector!(float, 2).init);
fun2(Vector!(float, 2).init);
}
Why can fun1 deduce `T`, but fun2 can't?
Failure:
"template d.fun2 cannot deduce function from argument types
!()(Vector!(float, 2))"?
