Which might well push execution down the unoptimized code path. Also,
ISTR that Steven's original timeit runs tacked on a standalone "eval ;
..." to the function call case, so the LOAD_GLOBAL bytecode would have
been done in the function call case as well. He was, I think, doing
what he could to make the two cases as nearly identical as he could.
