The reverse_verbose_map property method is inefficiently recalculating the reverse mapping every time it's accessed by iterating through verbose_map. ###### Why this matters Since verbose_map is also a property method, frequent access to reverse_verbose_map will cause repeated unnecessary computations which could impact performance for large datasets. ###### Suggested change ∙ *Feature Preview* Cache the reverse_verbose_map or calculate it once when verbose_map changes: ```python def __init__(self): self._reverse_verbose_map = None @property def verbose_map(self) -> dict[str, str]: verb_map = {...} self._reverse_verbose_map = None # Invalidate cache return verb_map @property def reverse_verbose_map(self) -> dict[str, str]: if self._reverse_verbose_map is None: self._reverse_verbose_map = {v: k for k, v in self.verbose_map.items()} return self._reverse_verbose_map ``` ###### Provide feedback to improve future suggestions [](https://app.korbit.ai/feedback/aa91ff46-6083-4491-9416-b83dd1994b51/e0fb7989-aed0-4041-98fe-0163f636ca0b/upvote) [](https://app.korbit.ai/feedback/aa91ff46-6083-4491-9416-b83dd1994b51/e0fb7989-aed0-4041-98fe-0163f636ca0b?what_not_true=true) [](https://app.korbit.ai/feedback/aa91ff46-6083-4491-9416-b83dd1994b51/e0fb7989-aed0-4041-98fe-0163f636ca0b?what_out_of_scope=true) [](https://app.korbit.ai/feedback/aa91ff46-6083-4491-9416-b83dd1994b51/e0fb7989-aed0-4041-98fe-0163f636ca0b?what_not_in_standard=true) [](https://app.korbit.ai/feedback/aa91ff46-6083-4491-9416-b83dd1994b51/e0fb7989-aed0-4041-98fe-0163f636ca0b) </details> <sub> 💬 Looking for more details?
