Anyone using regexes to pick apart a binary file format might use that.

eg my Palm::Treo680MessagesDB

but in that I consistently use \00 for a NUL, never \0.

Seems to me that \08 should scream and shout, because if it's meant to
match NUL followed by 8, then you should expect Pain if the programmer
ever has to change it to match NUL followed by 7, or NUL followed by 40,
or ...
