I'm upgrading from 4.0 to 5.0beta. One thing I can't really sort out
after reading the manual and the past mails is the globals. There is
suppose to be somthing called _glob (manual section 3.2) though some
mails refer it as _global or __global. Also there is a pseudo-index
called LUA_GLOBALSINDEX and the registry LUA_REGISTRYINDEX. When I
print them from interactive lua, they all return nil. Am I correct
that these values can only be assessed via C function calls? What
really are pseudo-indices? What are they designed for?
