[LLVMdev] about the namespace

[Nai Xia]

Hi,I apologize if it is a stupid question.
It seems that the style of using namespace in LLVM confuses my "source 
insight" and my ctags for correctly finding the implementation of a class 
member. For example, the implementation of members of Instruction class is 
written like this.

----------------
... ...
using namespace llvm;
Instruction::Instruction(...);
... ...
----------------

It seems that both sourceInsight and ctags trend to consider 
Instruction::Instruction(...) as "::Instruction::Instruction(...)"
instead of "llvm::Instruction::Instruction(...)".

So I am just curious about that why the code is not written like this:

---------------
namespace llvm {

Instruction::Instruction(...);
... ...
}
---------------

Is there any reason for choosing the former style?
