If you go back and read it I was talking about what seems like old vs. new coding pratices for .bml pages. I've found instances on my site in particular that variables weren't carying from the BODY=> are to other areas (including crumbs). I've foudn that if pages are coded in such a way that there is one large <?_code _code?> section before the <?page page?> section then all the variables carry across with no problem.
What I am proposing is that me (or someone else) go through all of the .bml files and convert them to use this method of coding. I have already started doing this on my LJ site and it wouldnt be a problem for me to submit patches to zilla if its decided that this will be used. Otherwise I'll just keep this stuff to myself.
I can't see how this will hurt, and it seems to me like a more efficient way of parsing the files, though I haven't really looked into the bml engine to see the internals.
Edit:
Yeah, I guess I kinda suck at asking questions. Basically, if the work is done and submitted, will it be used?
