 The compiler generates Python code by generating Python AST nodes, rather than emitting the raw Python code as text.
 This is convenient for the compiler, but inspecting Python AST nodes manually for bugs can be a bit of a challenge even with a debugger.
-For this reason, the Basilisp compiler can also use the :external:py:func:`ast.unparse` (`astor <https://github.com/berkerpeksag/astor>`_ in versions of Python prior to 3.9) library to generate raw Python code for visual inspection.

 Currently, the compiler is configured to automatically generate Python code for all namespaces.
 This code generation isn't slow, but it does add an appreciable amount of time to the compilation of each individual namespace.

+Basilisp includes a specialized set of reader features based on the major version of Python (e.g. 3.10, 3.11, etc.).
 Because the API of Python's standard library changes significantly between versions, it can be challenging to support multiple versions at once.
 In classical Python, users are forced to use conditional gates either at the top level of a module to define different function versions, or perhaps gate the logic within a function or class.
 Both options incur some level of runtime cost.
