Bencmark is very good!


   36 @  96.55% ..  99.99%
  245 @ 100.00% .. 100.99%
   28 @ 101.00% .. 109.99%
    7 @ 110.00% .. 119.99%
   10 @ 120.00% .. 129.99%
   29 @ 130.00% .. 199.99%
    4 @ 200.00% .. 299.99%
    1 @ 314.29%

so about 10% of tests became marginally slower - usually due to one extra
conditional in an op to test for a private BOOL flag or ReANY(); about 70%
of tests were almost unaffected, while 20% of tests showed improvement,
most with considerable improvement, and a few with spectacular improvement.
(The 314% is for an empty @lexical tested in boolean context).
