In R, named vector indexing is highly optimized (vectorized C code), while environment creation and mget() have overhead that outweighs the O(1) lookup benefit. Benchmark results (5000 members, hierarchy building): - Original (named vector): 354ms median - Optimized (env hash): 360ms median - Improvement: -1.6% (regression) Keeping P8 (vapply instead of sapply) which is a valid type-safety improvement.
