BTW, while we are on this topic, why the following is not in upstream yet? http://eigenclass.org/R2/writings/optimizing-caml_modify Looks like a clear win-win without drawbacks (increased code size shouldn't be significant cause Modify is only used in a couple of places). What do you think? PS I was hoping Mauricio will push it to bugtracker or start discussion but apparently this didn't happen so here we go - stealing the flag, sorry :) -- ygrek http://ygrek.org.ua
