I've encountered a bug with namespaces, if you create a object type inside of a namespace besides the global, then create a global property with the same name as the object type but in the global namespace,  the opIndex method fails. The following code should show whats going on more than my explanation

#include "angelscript.h"
#include <stdio.h>

void MessageCallback(const asSMessageInfo *msg, void *param)
{
	const char *type = "ERR ";
	if( msg->type == asMSGTYPE_WARNING ) 
		type = "WARN";
	else if( msg->type == asMSGTYPE_INFORMATION ) 
		type = "INFO";

	printf("%s (%d, %d) : %s : %s\n", msg->section, msg->row, msg->col, type, msg->message);
}

class FooObj
{
    public:
        FooObj() { };

        int operator[](int num)
        {
            return 1;
        }

        void test() { }
};

int main()
{
    asIScriptEngine *engine = asCreateScriptEngine(ANGELSCRIPT_VERSION);
	engine->SetMessageCallback(asFUNCTION(MessageCallback), 0, asCALL_CDECL);

    engine->SetDefaultNamespace("NSBugTest");
    engine->RegisterObjectType("FooObj", 0, asOBJ_REF | asOBJ_NOCOUNT);
    engine->RegisterObjectMethod("FooObj", "int opIndex(int)", asMETHOD(FooObj, FooObj::operator[]), asCALL_THISCALL);
    engine->RegisterObjectMethod("FooObj", "void test()", asMETHOD(FooObj, FooObj::test), asCALL_THISCALL);
    engine->SetDefaultNamespace("");

    FooObj foo;
    engine->RegisterGlobalProperty("NSBugTest::FooObj FooObj", &foo);

    asIScriptModule *mod = engine->GetModule("test", asGM_ALWAYS_CREATE);
	mod->AddScriptSection("test",
			"void main() \n"
			"{ \n"
            "   FooObj.test();\n"
            "   int num = FooObj[0];\n"
			"} \n");
	mod->Build();

    return 0;

}

The call to test() will work like it should, however the opIndex call generates the following error:

test (1, 1) : INFO : Compiling void main()
test (4, 21) : ERR  : Expected ']'
test (4, 21) : ERR  : Instead found '<integer constant>'

Thanks
