Convert code from one language to another
A literal line-by-line translation between languages often compiles fine and still isn't idiomatic in the new one.

- Anyone porting a piece of code from one language to another who wants it to read like it was written there natively.
Converting code from one language to another can produce a version that technically works but reads like the source language wearing the target language's syntax — literal transliteration instead of an idiomatic rewrite, which is harder to maintain and reads oddly to anyone familiar with the target language's real conventions. This prompt converts to genuinely idiomatic code in the target language, not a structural copy with swapped syntax.
When not to use this
If you need an exact line-by-line mapping for a specific technical reason (auditing against the original, say), idiomatic conversion isn't the goal — a literal translation is what you actually want there.
Did this work?
The converted code reads like it was written natively in the target language, using its own idioms, not a literal transliteration of the source language's structure.
