You know this must have been added since I started working with Lua.

Yes, but it is not as cute.

I think luarock depends on this somedirectory/?/init.lua at other places. If 
you search this bulletin board (probably dating myself with this 
appellation)for init.lua a number of people had mixed problems because of 
it. Nice not to be alone.

I am wondering how many people depend on the default path?

Anyway I learn one more thing about the Lua implementation. I will reread 
the luaconf.h file and may learn even more.

By the way nowhere is the LUA_PATH_DEFAULT documented in Lua documentation. 
I guess reading the source is a good idea.
