A metaclass in Python is a class of a class, meaning a class is an instance of its metaclass. We can use a metaclass to create a singleton by overriding its __call__ method to control the creation of instances. Here's how you can implement a singleton using a metaclass in Python: cl...
Nuitka starts by parsing the Python source code and building an abstract syntax tree (AST) representation of it. The AST represents the structure of the code and contains information about the code’s variables, functions, and control structures. Nuitka converts the AST into an intermediate repres...

The provided Fitness class is an abstract class that needs a weights attribute in order to be functional. A minimizing fitness is built using negatives weights, while a maximizing fitness has positive weights. For example, the following line creates, in the creator, a ready to use single object...

(almost 11k). Fine in the abstract, but it turns out that OpenType has a limit for how many lines of code can be in a single lookup table (around 3k – everything in a lookup table has to fit into 16 bits, because reasons), so compilation fails. There are definitely many ways ...
