[via Digitalmars-d-bugs]

--- Comment #1 from Vladimir Panteleev <dlang-bugzilla at thecybershadow.net> ---
I believe that this enhancement request is today possible to implement on top
of D's existing introspection / metaprogramming / code-generation features.

In either case, today enhancement requests to the language itself need to be
presented as a D Improvement Proposal:

Please file a DIP if you think this proposal still has merit today. The current
DIP manager can assist you through the process.
