Another thing I've found (by doing Lua bindings by hand) is that a
mechanical approach really doesn't make for good Lua bindings. Such a
mechanial approach to syslog() would end up with:
syslog(5,string.format("The foo is %s",status))
Or ...
LOG_NOTICE = 5
syslog(LOG_NOTICE,string.format("The foo is %s",status))
Or
syslog("LOG_NOTICE",string.format("The foo is %s",status))
Doing it by hand, I did [1]:
syslog('notice',"The foo is %s",status)
which is MUCH nicer (IMHO) than other syslog() interfaces for Lua I've seen.

It's true. I tried to map some OpenGL functions into Lua. It requires really flexible discretion to decide among multiple return, or return in tuple; vararg, or table argument, or merge several functions into a single Lua API. Not a mechanic approach being able to handle.
