Using dmd 2.062 on GNU/Linux, this prints:
  main: tuple(1)
  f: tuple()
  g: tuple(1)

void f(T)(T o) {
    pragma(msg, "f: ", __traits(getAttributes, o));
}

void g(alias T)() {
    pragma(msg, "g: ", __traits(getAttributes, T));
}

void main() {
     (1) int i;
    pragma(msg, "main: ", __traits(getAttributes, i));
    f(i);
    g!i;
}

Is this intended behavior?

It's intended behavior, because UDA is always associated with symbols. In template function f, `o` is a function parameter, and it is different symbol from the local variable i in main function. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
