Size_t on x86 is uint,on x64 is ulong,it's a good thing?
I don't think is ok.
it creates many convert thing,such as length is ulong ,must
cast to int or cast to uint. It will be waste of time ,I think.

It's the same in C and it reflects what the hardware is doing
underneath with regard to memory addresses. That's the point of
size_t. If it didn't change size then we'd all just use ulong

I should use the 'int'.

TkD is nice,but the exe's Memory usage is 6.8~7M,but DFL's only
2.8~3M,and only a single file on windows 7.
https://github.com/Rayerd/dfl,
I compare DFL with tkD and dlangui,find:
DFL can gets the smallest exe file and Minimal memory footprint.
Although it only works on windows,but it full wrote by D. and its
syntax is very similar to c#,that can help a lots of c# lovers
turn to D,this will help D to develop.
What's the status
Sweet, as I see it works and there's plenty of documentation
about swt.
Not much can beat a 2.6MB standalone application with a 2mb
footprint!
I test on windows 7,it's size is 2829k,with a 2836k footprint.
But DFL's is 778k with a 2724k.

Partial classes are used in C# wherever you need to combine
auto-generated code and user code into a single class. So,
the Windows GUI builder does it placing all the GUI component
construction and property setting in one file, and allowing
the user to only have to see/edit the application
No human uses partial classes in .NET land other than the tools
themselves.
It is a language feature introduced to simplify how Visual
