Interesting. Looks like this is an issue with aliases, because I get the error with this code too:

--- test.d
import std.typecons: Tuple, tuple;

alias Pair(T) = Tuple!(T, T);

void foo(T)(Pair!T p)

unittest {
    Pair!int x = tuple(1, 2);

Looks like this is the same problem described in issue 1807:


I'm not sure what D was like when Martin Nowak made the most recent comment on that issue, in 2012, but alias templates do have their own dedicated language construct now, so maybe this is worth revisiting.
