I agree that the current 'alias' feature is a useless and clueless facility.
However, it does exist. Therefore, to allow backward compatability a new key word
is required. If backward compatability is not an issue, then we do NOT need a new
key word.

But more importantly, I think that multiple instances of the same include file
is against RDS's programming philosophy and thus its not going to happen (in
Euphoria anyway).

Agreed. But it took ages, and many people hammering RDS for a namespace
solution. It seems that RDS deliberately chose the smallest subset that would be
easy to implement and solve most issues people were concerned about. I agree that
this compromise gave us a crippled product. My point is though, I don't think
that RDS is not going to radically change it again. In 2.5 we are told that there
will be a small improvement, but that's all I would expect in the namespace
functionality from RDS.

I hope I'm very, very wrong.
