Re: work4 - loadfile and packaging

[Mark Hamburg <mhamburg@...>]

If dofile were to take extra parameters, it might be better to have it take
an environment:

    function dofile( name, env, ... )
        local f = loadfile( name )
        if env then
            setfenv( f, env )
        end
        return f( ... )
    end

Or go all out and specify it as:

    function dofile( name, dir, env, ... )
        local f = loadfile( name, dir )
        if env then
            setfenv( f, env )
        end
        return f( ... )
    end
