If the transform calls `map_core` or another library name, load the [core distribution](/sutl/core-library) and compile its requirements; the full fixture retains that library context.\n\n[Full original fixture](https://github.com/emlynoregan/sutl-language/blob/0c3463677495ea00767f8266ae900eb4e2f98617/fixtures/studio/410f7dda-823c-868d-c0a7-5de3832c5eb8.json) · [Curated source record](https://github.com/emlynoregan/sutllang-site/blob/e59ecafd364848cd71a1d18ce74cdf67f2f69328/content/examples/curated/ifbuiltin-sutllang-emlynoregan-com--410f7dda-823c-868d-c0a7-5de3832c5eb8.json)\n\n## Related reading\n\n[Paths](/sutl/guide/paths) · [Quoting and evaluation](/sutl/guide/quoting-and-evaluation) · [Libraries](/sutl/guide/declarations-and-libraries)\n\n## Source\n\nAdapted from [the sUTL source material](https://github.com/emlynoregan/sutllang-site/blob/e59ecafd364848cd71a1d18ce74cdf67f2f69328/content/examples/curated/ifbuiltin-sutllang-emlynoregan-com--410f7dda-823c-868d-c0a7-5de3832c5eb8.json).\n\n[Back to sUTL](/sutl) · [Software & Agents](/topics/software-and-agents) · [All topics](/guide)","author":"Emlyn O'Regan"}}
