--- Comment #1 from John Hall <john.michael.hall@gmail.com> ---
It seems that this is related to not having a module defined...

When I add something like
module A;
to the top and then
static assert(__traits(isDisabled, A.foo));
compiles without error when U is there and if U is removed then it gives the
error that T is not defined.
