Thanks!

I did not make any performance measurements. If you know how 
could I do this at compile time, it would be awesome. I think, I 
would need to watch the compiler process for this. If there is no 
other way, I'll do it like this after I will have a more concrete 
APIs.

Usually templates take more time to compile that CTFE, that's why 
I intend to use less templates, or none, if is possible. I expect 
to see an increase in the compilation time, but It should not be 
exponential. I am doing this, because I work a lot with 
introspection, and some of my projects are hard to read because 
of all this mess around traits an templates.

That made me think that, I could give a few more seconds to the 
compiler to have a more readable code. I'll update my projects to 
use this library to see how the compilation performance will 
change.
