Thank you for your great contribution, I started porting from 
github to wiki here

By any chance, do you use gmail? The email sent by the wiki 
appeared in my gmail's spam.

Yes, I use gmail, but the domain name is the same as my current 
username here. I requested again to send confirmation e-mail, no

Forgot semicolon in hello world example.

Anyway, I'm already asking for help from experienced D users to 
translate the following concepts in D:


- decimal type
I heard, there was an implementation of a scaled integer and a 
rational type.

- dynamic types

No exact equivalent, opDispatch is similar, but is compile-time.

- volatile

atomicLoad, atomicStore

- boxing/unboxing

Variant

- multicast delegates
- events

std.signals (needs rewrite)

- yield return

input/output ranges

- P/Invoke
Not really needed for native languages, because they interface 
with the platform directly. Well, there are utilities like 
tempCString.

- async/await
vibe addresses the same problem 
http://code.dlang.org/packages/vibe-d

- linq

std.algorithm, std.range, std.array

- runtime reflection

Nothing builtin, D relies more on compile-time reflection.

- serialization

http://wiki.dlang.org/Libraries_and_Frameworks#Serialization

- inlining

only http://wiki.dlang.org/DIP56

- weak references

To be implemented in druntime

- implicit casting overload

Not supported deliberately, as I understand it

- COM imports
There was some attempt at COM integration, not sure how far it 
has gone. AFAIK, COM can expose interface as IDispatch, that 
would save one from parsing the type library manually.

- templated functions override

Done by redirecting templated function to non-templated one.
I'm not asking for solutions (because I know how to implement 
them in D), I'm asking for guidance about the best D semantics 
to be used instead.
Do things at compile time, allocate as little as possible, in 
other words, be efficient.

I could add something for Ruby but I'm not really sure what to 
add. The the content for the existing languages is quite 
different compared with each other.


This is a wiki, so do it the way you want.

Personnaly for the Delphi/Pascal section i haven't followed any 
previous model (except for the `pascal way` or the D way`) but 
i've rather choosen to focus on ambiguities and similarities...


Just do it and if someone comes with a better solution he can 
delete everything. It'a wiki.

BTW - respect for doing this.  Will try to learn from what you 
have done.


When these pages are mature, maybe they should be linked from the 
front page sidebar.

Great - let me know if you want me to add something when ready.  
There must be a markup to wiki converter somewhere.
