I think we just using new for garbage collection memory allocation and for
someone that using new for memory management by themeselvs will misleading!

In D the "default" is generally the safer way (that here is the GC way), this
allows the programmer to put less bugs in the code.

Yes, gc is more safe, but also there is a keyword delete, is there any conflic
here? I don't know if there conflict here. If I alloca memory space by gc, and
delete it by hand, is there any conflict will happen?

No. It will work fine.

In a reference counting GC the detele isn't a way to delete memory by hand, it
tells the GC to remove a (hard) refence to some memory. Later the GC can really
remove the memory only if there aren't references to it left (this is in a
reference counting GC, but in other GCs the final results are similar).

If you want C++, you know where to find it.  If people are thinking in C++ 
while programming in D, they shouldn't.

Changing D's new/delete to be for manual memory management would break 
nearly every D project ever conceived.

Besides, such a change would make it appear that the 'normal' way of 
managing memory in D is manually, and GC is the alternative.  Quite the 
opposite of the way D is designed.

Besides, even if we did have this, would it:
- be just syntactic sugar for malloc/free?
- allocate on a third heap, besides the malloc heap and the GC heap?
- allocate on the same heap as GC memory, but with a flag not to GC it?
- something else?

Stewart.
