This code used to compile: --- enum t1(T) = __traits(compiles, { T; }); enum t2(A...) = 1; template t3() { struct S; alias t3 = t2!(t1!S); } void main() { alias t = t3!(); } --- main.d(8): Error: alias main.t3!().t3 recursive alias declaration main.d(8): Error: template instance t2!(t1!(S)) recursive template expansion main.d(8): Error: alias main.t3!().t3 recursive alias declaration main.d(8): Error: alias main.t3!().t3 recursive alias declaration main.d(8): Error: template instance main.t1!(S) error instantiating main.d(13): instantiated from here: t3!() ---

Opened Issue 14090. Sorry it's not that reduced.
