dynamic_apply -- apply `f.call` to `Any.this`'s dynamic type and value
This can be used to perform operation on values depending on their dynamic type.
Here is an example that takes a `Sequence Any` that may contain boxed values of types `i32` and `f64`. We can now write a feature `get_f64` that extracts these values converted to `f64` and build a function `sum` that sums them up as follows:
