hello everybody,

i'm new to this language and plan to start learning it by porting parts

i would very much appreciate it if you have some tips & tricks, hints of 
pitfalls or any other experiences to share.

Well I've ported quite a bit of C++ code to D.
And on the whole I'd say that there isn't really much to say.

Most of the issues I've hit have been bugs in dmd or optlink;
which clearly have nothing to do with the language itself.

Unless you need pointer to members/pointer to member functions, just 
about every bit of c++ is easier and more straight forward in D.

Just plough ahead and ask questions if you hit an issue.

I have had some problems when the original C++ code uses struct inheritance
("alias this" helps a bit) or multiple inheritance.

Most well written C++ only uses MI for pasting methods into classes; you 
can mostly re-factor code like that into template mixins.

When I've come across C++ which isn't easily convertible to D, then the 
original code itself is badly written and badly designed anyway, so I 
don't even want to port it.

Easier just to write it again in D
