I know it might not be the most idiomatic D, but as somebody
with mostly a Java background (with some C and just a bit of
C++) it seems something really straightforward to me:
myObject.getClass().getFields() [2].
Also, I know I could add some UDA or even crawl the modules and
have this information generated automatically at compilation
time and added to the type itself in a member, and I might even
end up doing it, but honestly, I think it's something that the
language should provide in a kind of easy / accessible way.
Powerful as compile-time introspection is, I think runtime
shouldn't be forgotten either :-)
Thanks,

There is a library that creates reflection metadata for you. [1]
It seems a bit outdated and has some not-that-obvious compilation
errors(for example getting ctor and callling it with runtime
known type, or some other non template stuff), but other than
that seems to be working (note that I didn't thorougly tested it,
but its unittests succeeds on DMD 2.080 for both Windows x86
mscoff & x64 )
