[pooma-dev] Compile Time Problems and Pooma 2

[Scott Haney]

Hi Dave,

The root problem is that you want to blindly take the output from KCC 
and use that to guide pre-instantiation. This is certainly the easiest 
thing from your perspective, but it presents an almost insurmountable 
problem from our perspective in that we have to guarantee that every 
template can be instantiated in any possible order. I don't think we can 
do this in all cases. This means that your tool needs to get slightly 
smarter to handle the small set of exceptions where order does matter. 
For the case you're describing, you need to pre-instantiate some stuff 
from Field before you hit AltView1, etc. I expect that the number of 
exceptions is quite small and could easily be added to your scripts.
