Based on recent discussions on the NG a few features were
deprecated/removed from D, such as typedef and C style struct
initializers.
IMO this cleanup and polish is important and all successful
languages do such cleanup for major releases (Python and Ruby come
to mind). I'm glad to see that D follows in those footsteps instead
of accumulating craft like C++ does.
As part of this trend of cleaning up D before the release of D2,
what other features/craft should be removed/deprecated?
I suggest reverse_foreach and c style function pointers
please add your candidates for removal.
s/reverse_foreach/foreach_reverse/ ;)
1. Floating point literals without digits on *both* sides!!! "1.",
".1" --> Useless hindrance to future language expansion!
2. Octal literals! I think it'd be great to have a new octal syntax,
or even better, a general any-positive-inter-base syntax. But until
that finally happens, I don't want "010 == 8" preserved. And I don't
think the ability to have an octal literal is important enough that
lacking it for a while is a problem. And if porting-from-C really has
to be an issue, then just make 0[0-9_]+ an error for a transitionary
period (or forever - it'd at least be better than maintaining "010 ==
8").
3. Also the comma operator, but that's already been recently discussed.
<bikeshed>
hex literal prefix: 0x, not 0h
=>
octal literal prefix: 0c, not 0o
</bikeshed>
This I'm on board with. 0o is too much like a practical joke.

in the short term I wouldn't mind if they would be typed as:
0baseEightXXX or what ever as long as the current syntax is removed.
in the long term, I'd like to see a more general syntax that allows to
write numbers in any base.
something like:
[base]n[number] - e.g. 16nA0FF, 2n0101, 18nGH129, etc.
also define syntax to write a list of digits:
1024n[1005, 452, 645, 16nFFF] // each digit can also be defined in
arbitrary base
What's the point of using bases other than 2, 8, 10, 16, 36 and 64?
