Well, I understand that using floating point values to represent time
internally is a bad idea and I totally agree. But some convenient API
to convert Duration to floating point and vice versa would be useful
because in mechanics for example you often need to express time in
seconds with fractional part. In this regard std::chrono is more
expressive (the only one though, in general std.datetime is much more
powerful than std::chrono).
If you need a real (double, float) parameter, just use it. Transport the
units separately...
Could you elaborate what you mean?
```
auto point = vec3(1.0, 2.0, 3.0);
vec3 velocity = ...;
auto t = dur!"msecs"(500);
...
auto new_point = point + velocity * t.total!"msecs"/1e3;
```
How can I use a real parameter and transport units separately here?
