 reactive API
 
 `rx` is a wrapper around a Python object that lets users create

+The original input to an `rx` object is stored in a mutable list and can be
 accessed via the `_obj` property. The shared mutable data structure
 ensures that all `rx` instances created from the same object can
 hold a shared reference that can be updated, e.g. via the `.set`
 method or because the input was itself a reference to some object that
 can potentially be updated.

+When an operation is applied to an `rx` instance, it will
 record the operation and create a new instance using `_clone` method,
 e.g. `dfi.head()` first records that the `'head'` attribute is
 accessed, which is achieved by overriding `__getattribute__`. A new
 reactive object is returned, which will then record that it is

 `rx` implements `__call__`. `__call__` returns another
 `rx` instance. To be able to watch all the potential
 operations that may be applied to an object, `rx` implements:
