Currently, D header files don't support either of those features. You 
probably need a custom header generator, one that pays attention to UDAs 
(assuming you want to annotate functions according to whether they can be 
called at compile time; otherwise, there's a fair bit more work).

Unfortunately, DMD's json output doesn't even write UDAs, so you can't 
use that to write your own header generator.
