  Well, to me D has two significant drawbacks to be "ready to use". The
first one is that it doesn't has bit-fields. I often deal with bit-fields
on structures that have a _lot_ of instances in my program, and the
bit-field is chosen for code readability _and_ structure size efficiency.
I know you pretend that using masks manually often generates better
code. But in my case, speed does not matter _that_ much. I mean it does,
but not that this micro-level as access to the bit-field is not my
inner-loop.

  The other second issue I have, is that there is no way to do:
  import (C) "foo.h"

  And this is a big no-go (maybe not for git, but as a general issue)
because it impedes the use of external libraries with a C interface a
_lot_. E.g. I'd really like to use it to use some GNU libc extensions,
but I can't because it has too many dependencies (some async getaddrinfo
interface, that need me to import all the signal events and so on
extensions in the libc, with bitfields, wich send us back to the first
point).


  I also have a third, but non critical issue, I absolutely don't like
phobos :) Though I'm obviously free to chose another library. D has
definitely many many many real advances over C (like the .init, .size,
... and so on fields, known types, and whatever portability nightmare
the C impose us). In fact I like to use D like I code in C, using
modules and functions, and very few classes, as few as I can. And even
(under- ?) using D like this, it is a real pleasure to work with. I'm
really eager to see gdc be more stable.
