Re: Please, help with this scope problem (simple?)

[Blake Huff <stangmechanic at gmail dot com>]

I'm pretty bad with this, but here's my guess:   What if B had  
multiple templates, i.e., A, C, D, and E,  which each had their own  
i?   Compiler needs to know where to go.   Someone else might have a  
better technical explanation (or maybe I'm wrong altogether!).
