Yep. I 100% agree.

The issue with D right now are not the bells and whistles.
It's the bread and butter.

As for the template emission, having been away from the issues 
and scene for a while made me realize the reason of the emission 
issues.
It's that we cannot emit the same symbol twice.

@Ibuclaw if I am correct at least that would be solved by making 
template instances weak symbols no?

If we did that we could remove some complexity from the emission.
