Re: SDL package (namespace problem)

[Asko Kauppi <asko.kauppi@...>]

it was nice to get much attention to the naming issue.

in fact, i've already started work on 'sdl_wrap.lua' (part of gluax 
2.18) that uses the SDL.* notation. However, it does this by 
redirecting the original (C++) module's function, and enhancing some of 
them. For compatibility reasons, i keep the 'old stuff' as they are.

In gluax, you can either say USES 'sdl' (for the old interface) or USES 
'sdl_new' (for the new one).

Seems like that wrapper should be brought to LuaCheia, too.

-ak

p.s. it is quite possible to enforce not using global namespace. i've 
done that, with modules that themselves think they're putting stuff to 
global. Eventually (for apps) it becomes something_else.*
