After taking a deeper look into this, I realized that I may be misunderstanding how enums are supposed to be used.  Does it make sense that you'd provide an enum name as a type to get static type checking?  Like this...

<code example>
type TEST_ENUM: enum { test_one, test_two, test_three };

function blah(b: TEST_ENUM)
	{
	print "did it work?";
	}

event bro_init()
	{
	local a = test_two;
	print blah(a);
	}
</code example>

I get this error from that code..

[seth at Blake build (master)]$ ./src/bro test.bro 
./test.bro, line 11 (print blah(a)): error, value of type void illegal

Before I send my example for namespaced enums, I think I need to get more of the base usage of enums clarified.  Are there any examples that you know of where enums are used as parameter values like this?
