Sometimes, though, we need to print documentation back, for 
example when writing a command line tool and "-h" is passed.

I suggest `__traits(ddoc, symbol)`, which would return the 
concatenated DDoC source of a symbol as an enum string.

If DMD compiler authors provide pointers (where to start, what 
methods to call) on how to do this, I will implement this myself 
and send a pull request.

This has been proposed and implemented before, but it was not 
accepted into the language. See:

This is the same use case I had:
