IndexWhere
Generated from the engine's own definition: compute-engine's symbol, which we neither extend nor document by hand. No examples yet — the crosswalk is the reason it has a page.
Return the 1-based index of the first element satisfying the predicate, or 0 if not found. Stays unevaluated when the collection cannot be searched (a symbol with no value, an unbounded source with no match).
