Is deprecating a template supposed to work?

[aliak via Digitalmars-d-learn]

Is this suppose to give a deprecation error message?

deprecated("a")
alias A(T) = B!T;

template B(T) {
    alias B = T;
}

void main() {
    A!int a; // should this cause a message "a" ?
}

??

Or am I using it wrong maybe?
