[development] coding standard question

[mark burdett]

well,  it seems like coin tossing to me. But I haven't let it run all day.

in this test, TRUE wins:
mark at subtle ~/Sites % php pp/test.php
  true: 1.26725101471  TRUE: 1.25381183624
  true: 1.29299092293  TRUE: 1.26070404053
  true: 1.27665114403  TRUE: 1.24824905396
  true: 1.31866884232  TRUE: 1.25040316582
  true: 1.27103209496  TRUE: 1.2434129715
  true: 1.28510403633  TRUE: 1.24616312981
  true: 1.29535198212  TRUE: 1.24373793602
  true: 1.27827787399  TRUE: 1.22749304771

in this one a tie:
mark at subtle ~/Sites % php pp/test.php
  true: 1.26420211792  TRUE: 1.24726390839
  true: 1.25392603874  TRUE: 1.25495100021
  true: 1.25082397461  TRUE: 1.24722003937
  true: 1.25069499016  TRUE: 1.24976992607
  true: 1.25077605247  TRUE: 1.247205019
  true: 1.25090909004  TRUE: 1.25059509277
  true: 1.30386614799  TRUE: 1.31354403496
  true: 1.2652528286  TRUE: 1.25868320465

TRUE wins another one:
mark at subtle ~/Sites % php pp/test.php
  true: 1.23990178108  TRUE: 1.21928906441
  true: 1.22088694572  TRUE: 1.21982097626
  true: 1.21747803688  TRUE: 1.22024011612
  true: 1.21896100044  TRUE: 1.22330522537
  true: 1.22763895988  TRUE: 1.2149310112
  true: 1.21694612503  TRUE: 1.21505308151
  true: 1.21890115738  TRUE: 1.21598815918
  true: 1.21745586395  TRUE: 1.21514201164
