🎤 *SPy: high-level Python, low-level performance, no overhead by Antonio Cuni*
🔗 https://ep2026.europython.eu/session/spy-high-level-python-low-level-performance-no-overhead

📝 Abstract:
SPy is a Python variant designed for compilation: well-specified, debuggable, and expressive. It consists of a low-level core which gives control and speed comparable to C, Rust and Go, and powerful metaprogramming features which make possible to build high-level zero-cost abstractions. The result is something which is statically typed and as fast as C, but with the feeling and ease of Python.

This talk is a deep dive into the SPy core ideas: in particular, we will explore the internals of the language, show how many builtins are implemented in SPy itself, what "zero cost abstraction" means in practice and some end-to-end example of how high-level Python code is compiled into a low-level fast executable.
