I had one project where I had to solve the same problem both in 
C# and in D.

In C# I first used 'dynamic' for prototyping.
+ Simple
- Slow
Later I had to optimize it by doing "RT introspection" and 
caching the result.
+ Fast
- Somewhat complex

Adams proposal is both simple and fast out of the box.
