Status: OUT
Python's language-level defaults — particularly Counter's zero-default for missing keys and sentinel initialization for loop state — are a primary mechanism that makes streaming self-sufficient by encoding boundary conditions into initial state, removing the need for special-case logic in loop bodies. Because streaming is the privileged default strategy (self-sufficient, covering the largest problem subset with the tightest resource bounds), these defaults help explain why streaming occupies its dominant position in the solution taxonomy: the language's built-in semantics align with the prerequisites of the strategy that needs the least external support.
unique contributions are defaults-encode-domain-knowledge + three-strategies-cover-taxonomy; combined, language design participates in shaping the taxonomic structure
