But `%h` is a lexical variable too, and the point of the exercise is to access that. toby döt ink	[reply] [d/l]

The point was to assess the relative difference `exists $h{$k}` vs `$h{$k}`, not the absolute speed. A few more details are in 11111212. Apologies for the confusion and/or lack of clarity.	[reply] [d/l] [select]

Yes, the lexical variables are part of the absolute timings. However, it's the relative timings that are of interest in this case as the point of the exercise was to assess the difference between `exists $h{$k}` or `$h{$k}`. If all other components are held constant then the timing differences should be due to the use of either of the two idioms (noting that the benchmarks need to be updated given dave_the_m's comments in 341121).
