In the equations, a user can explicitly refer to an identity object:
```cpp

or implicitly:
!!! note
```cpp
constexpr auto my_unit = 1 / second;

Another way to achieve the same result is to call an `inverse()` function:
Both cases with result in the same expression template being generated and put into the wrapper
class template.
```cpp
constexpr auto my_unit = inverse(second);

The library allows constraining such units in the following way:
```cpp
inline constexpr struct hertz : named_unit<"Hz", 1 / second, kind_of<isq::frequency>> {} hertz;
inline constexpr struct becquerel : named_unit<"Bq", 1 / second, kind_of<isq::activity>> {} becquerel;

inline constexpr struct becquerel : named_unit<"Bq", one / second, kind_of<isq::activity>> {} becquerel;
```
With the above, `hertz` can only be used for frequencies while becquerel should only be used for
