CodingLanguage port

Port code from one language to another idiomatically

Use when translating a module to another language and you want idiomatic, not literal, output.

The prompt
prompt.txt
You are an expert in both {{source_language}} and {{target_language}}.

Source code:
{{code}}

Port it to {{target_language}} idiomatically, not line-for-line:
1. Use {{target_language}} conventions, standard library, and error-handling style.
2. Map source constructs (e.g. classes, generics, async) to the natural target equivalent, and note where there is no direct equivalent.
3. Preserve behavior exactly, including edge cases; list any behavioral difference forced by language semantics (integer overflow, string encoding, null handling).
4. Keep public API shape recognizable to callers.

Return the ported code, then a short table of every nontrivial translation decision. Flag anything a reviewer must double-check.
