import std.stdio;

struct Foo
{
    int a;
}

int bar()
{
    writeln();
    return 1;
}

void main()
{
    Foo x = Foo!(bar());
}
---------------

A template argument is (accidentally) being passed to Foo. The compiler should,
and does, print a "not a template declaration" error. But before doing so, it
evaluates the completely erroneous template arg, resulting in a big pile of
totally non-applicable error text ("cannot be interpreted at compile time")
which obscures the one real problem.
