Finally, by the time you have implemented reflection, introspection, a decent
plugin system and meta objects in your C++ application you've inevitably
Greenspunned yourself a dynamic language anyway. Why bother, when you can take
Python off the shelf?<

I presume in large C++ programs those features are useful. A way to solve this
problem is to give those features to D. An alternative solution is to make D
very easy to interoperate with a dynamic language as Python/Lua/Ruby. A third
way is intermediate, this means adding more static introspection to D, and
allowing for an easy interfacing between D and a dynamic language. This third
way may be the best.

One another thing is the environment you like to work with and this is his  
real point IMHO. He likes to work in a dynamic typed environment like  
Python, and when it is not enough he switches to another language. Those  
who like to work in a static language had/have no choice, but D.

There are many static languages that support reflection, plugin systems
and meta-objects.

Actually one of my disapointments with D was that after reading the TDPL
I did not found any example of such features in D.
