Right. 

I am currently generating some code that does #using "bool.dll" (which
contains a namespace mercury.bool).

If I don't do that it doesn't get confused about bool.

It's because it's inside namspace mercury, and there is a namespace
bool inside that namespace.  

#using <mscorlib.dll>
#using "bool.dll"
namespace mercury {
void foo(void) {
        bool i;
}
}


The strange thing is if you use
 	using namespace mercury;
instead of being inside the mercury namespace, you get a resonable error
message.  And if bool is a top-level namespace, you get no error message
at all.

I agree.
