What you're talking about essentially results in a @world set which |
43 |
varies depending on the context. I'm not so sure that's a good idea. I'm |
44 |
inclined to suggest that you just use a different profile for each |
45 |
context (like the stage3 profile that I suggested in my reply to Ian). |
