How Python was Shaped by leaky Internals, Armin Ronacher, Flask framework

Armin Ronacher, creator of Flask, explains how CPython's internals and C API leak into the language's semantics. Using examples like the complexity of the add operation, he shows why Python is hard to optimize or reimplement.

“This excellent talk describes how the semantics of the "add" operation are much more complex than generally described.” Read on HN ↗
