Workload & symmetry rules

Workload

Generate 500 slices of 100 uint32 values via LCG; apply GenericSum, GenericMax, GenericMin to each, XOR-folding results. Repeat with 500 slices of 100 int64 values, the same generic functions in a second instantiation. Total 6,000 generic dispatches per outer call, each iterating 100 elements.

Symmetry rules

  • Go uses real [T Numeric] generics; Python uses the equivalent duck-typed function (it has no separate generic-dispatch primitive, so the comparison is what Python's runtime cost looks like on the same workload).

Why this benchmark exists

Distinct from interface dispatch (bench 13) and closure dispatch (bench 17). Measures whether piko's generics path has competitive specialisation.
