Re: Expression statements

I'm pretty sure (though not 100%) that that's just for C
compatibility, since win32 is a C API after all. C didn't have
dedicated true/false keywords before, and I *think* that true == 1 and
false == 0 still.

The typical Lua convention is to return nil, <error> on error, and
whatever the result is on non-error. It's not a hard-and-fast rule,
but some functions depend on it (like assert()).
