Error appeared when I defined opCmp and now I can't understand
what's the reason of the error. Why does tween need access to
unittest?
Try to use static struct instead of a struct.

And you need to use opEquals:
unittest {
static struct Point2D {
double x, y;
bool opEquals(const Point2D rhs) const {
return false;
}
}
auto p2d0 = Point2D(0, 0);
auto p2d1 = Point2D(1, 0);
assert(tween(p2d0, p2d1, 1 / 3.0) == Point2D(1

Thank you! It works. But where can I read about this issue?
Reading about this issue is not good. What you can read about
is how unittests are implemented in D (as functions) and what's
the difference between static structs and nonstatic ones when
they are defined

I guess I should

I guess I should read how tepmlates work.
No templates are involved in this code.

I mean that nested struct Point2D has additional pointer to frame and
when compiler tries to instantiate template function 'tweet' it
