I started to play with D last week and ran into this very quickly. I was
writing bindings for some application I wrote
(http://auriga.wearlab.de/~alb/nmdb/ is the app, you can browse the
bindings at http://repo.or.cz/w/nmdb.git?a=tree;f=d) and I needed to
raise an exception where a key in some kind of associative array was not
found.

I looked up to see the standard hierarchy only to found out there was
none, which was a bit of a bummer (the biggest one so far, because D
looks quite nice).

Then I tried to use the same one used by the standard data type, but it
required I give a file and a line number to it, which wasn't very clean
either.

Finally I had to implement my own, but it would have been much better to
have some standard hierarchy to use, or at least to have as a
"recommended style reference" for names and inheritance.

Are there any plans to work on this?

Thanks,
